what dissolves better in cold water salt or baking soda?

Why not try it?\nYou will have to come up with a way of using small amounts of each to keep it fair; perhaps a toy spoon from a doll's set.\nYou'll need to use the same amount of water for each test.\nAfter each addition, the solutions should be stirred by the same amount.

Vinegar is an acid (Acetic Acid) and baking soda is a base (Sodium Bicarbonate). Mixing acids with bases produces what is called "Acid Reduction Oxidation," or "Redox" reactions. Its basic forms result in salt (the type of salt is dependent upon the mixed chemicals), water, and heat (left over from the reaction). In the case of more complex reactions, where there is enough heat to separate some of the salt compounds, gases such as carbon-dioxide may alo be formed. \n\nThis is what creates the bubbles found in your "volcano."

They are chemical cousins but not identical  Baking soda is sodium acid carbonate, NaHCO3, while washing soda is sodium carbonate, Na2CO3.  Whether you can get away with the substitution depends on the nature of the project.

Yes they are the same.  Don't mistake Baking Powder though, that is different.  Baking Soda is Sodium Bicarbonate.

Alka Seltzer dissolves in water because it chemically reacts with water.\n\nThe chemical formula for this reaction is:\nH2O + Na(HCO3) --> CO2  +  NaOH  +  H2O \n\nThe equation is balanced.

1 tbsp baking soda and 1/2 tsp lemon juice this will whiten and does not have the explosive properties of baking soda and hydrogen peroxide

If they are insoluble, just dissolve the salt, then filter the solution, then dry it. Pure salt!

When I do this, I use mostly sodium bicarbonate and very little water (just enough to dissolve the baking soda). The point is that the acid is very damaging, so you want to make darn sure that you've neutralized it. The baking soda is not dangerous, so you don't worry if you use excess baking soda. \n\nWhen you're done, and have neutralized the acid, you rinse everything thoroughly with plain water.

acetates are ionic, and will more easily dissolve in water than an oil. thats your best bet.

chemical reaction\n-------------------\nBaking soda added to water raises the temperature slightly. Chemical reactions are either endothermic or exothermic. Endothermic means you have to put energy (heat) in to make the reaction go while exothermic means there's energy (heat) left over. Left over heat will raise the temperature. Baking soda and water is exothermic and so the water gets a little warmer. This is because the binding energy of the chemical bonds of the products has an excess over the binding energy of the components. Therefore, energy is released and the water warms up.\n\nEndothermic reactions do not usually go off at room temperature without heating. Baking soda is NaHCO3 and water is H2O. Added together you get NaOH and H2CO3 which are sodium hydroxide and carbonic acid. Carbonic acid is the fizz in soda. Eventually the mixture releases CO2 gas when the H2CO3 breaks down into H2O and CO2. The solution of H2O and CO2, if left alone uncorked, will lose its fizz. The water CO2 mixture will cool off slightly when the fizz (CO2) is released because the CO2 takes some energy with it. As the water evaporates it cools off because the warm molecules of water evaporate first! That's right! The warm ones!\n\nWhen we say temperature we really mean the average temperature of the molecules in a glass of water. Some are colder than average, some are warmer and many are close to the average. Evaporation requires energy, called the latent heat of vaporization. This heat comes from the warm water molecules. When the water evaporates it cools the glass off. That's why sweating makes you cool off too.\n\nA reaction that is endothermic will take place at a much slower rate because there are always some warmer molecules in the mixture. When we warm up the chemicals we raise the average temperature and a lot of the molecules can then react. When you mix bread dough the mix usually gets noticeably warmer after you put in all the ingredients. This is probably safe to try out at home with some adult help. Just ask your folks to help you whip up a batch of "soda bread." You can eat the result!

At 10°C, saturated solution of potassium chloride is more concentrated than potassium nitrate. At this temperature, potassium chloride completely dissolves while potassium nitrate would form some precipitates. At 60°C, it would be the same since both would completely dissolve at this temperature.

hey hun....i have red before to mix a little (tsp) of baking soda with a glass of water....i have never tried it before but if you get adventuress and try it let us know how it work out....love daisy

Chalk is a calcium salt, and as such will probably dissolve in an acidic environment. Try  some common acidic liquids like seltzer (a weak acid) , vinegar or lemon juice.

If you make them the same concentration (say 1 molar of each) the salt water will have a lower freezing point, and so will need to be colder before it freezes.  Freezing point is affected by the concentration of particles dissolved in the solution.  Since salt forms two ions and sugar forms only single molecules, you have more particles in a salt water solution than you do in a sugar water solution.

Salt occurs as (Na+Cl-) \nThe water molecules come between the atoms of salt , and thus breaks the ionic bonding b/w Na+ and Cl-.Na+ is attracted to the lone pair of oxygen atom of the water molecule and Cl-to the H atom of water molecule , thus hydrolysis and solvation of salt occurs, which makes the salt to dissolve fast whereas in sugars, the molecules are quite big and moreover sugar has a planar geometry , and contains bonds like -C-H, -C-OH-, -C-O-C-, these breaking of these bonds require more energy and moreover -C- is non-polar, thus increasing the no. of C atoms will make a compound to dissolve less in water. Sugar has 6 Carbon atoms.\nThus to dissolve sugar , we need stirring.

Baking soda is sodium bicarbonate (sodium hydrogen carbonate) and vinegar is acetic acid. One's an acid and one's a base. The sodium in the baking soda is a spectator ion, meaning it doesn't participate in the reaction. This means we don't have to write it.\n\nHC2H3O2 + HCO3- --> C2H3O2- + H2CO3\n\nCarbonic acid, H2CO3, dissociates into water and carbon dioxide. The full net ionic reaction is:\n\nHC2H3O2 + HCO3- --> C2H3O2 + H2O + CO2\n\nThe bubbles/foam you see is the CO2 gas.\n\n\nHope this helped.

Mmmm... Salt....\n\nYou will get a super-saturated solution. Like the sugar they use to make rock candy, salt dissolves better in hot water. Saturated means it has as much solute (salt, in your question) in it as will possibly dissolve, so a saturated solution at 60 degrees celsius has quite a lot of salt in it!\n\nAs the saturated solution goes back to normal temperatures, it eventually reaches the point where there is MORE salt in solution than would normally dissolve. This is called a super-saturated solution. It still looks like it did before, except saltier than normally possible.\n\nSeveral things can happen to a super-saturated solution as it cools. Either it appears unchanged, or crystals start to grow like when you are making rock candy. You would see crystals around the edges and on the sides and bottom of the container. Some substances like sodium nitrate are so soluable that they can crystalize all at once when disturbed, which looks like the solution instantly froze solid. Table salt does not normally do this, so just write that it would go from saturated to super-saturated and crystals would form.
