how is halite formed?
80972
Halite is found in many current evaporative deposits such as near Salt Lake City, Utah and Searles Lake California in the U.S., where it crystallizes out of evaporating brine lakes. It is also found in ancient bedrock all over the world where large extinct salt lakes and seas have evaporated millions of years ago, leaving thick deposits of salt behind. The cities of Cleveland and Detroit rest above huge halite deposits that are mined for road salt.\n\nHalite is the mineral form of sodium chloride, NaCl, commonly known as rock salt. Halite forms isometric crystals. The mineral is colourless to white, light blue, dark blue, and pink. It commonly occurs with other evaporite deposit minerals such as several of the sulfates, halides and borates.\n\nHalite occurs in vast beds of sedimentary evaporite minerals that result from the drying up of enclosed lakes, playas, and seas. Salt beds may be up to 350 m thick and underlie broad areas. In the United States and Canada extensive underground beds extend from the Appalacian basin of western New York through parts of Ontario and under much of the Michigan basin. Other deposits are in Ohio, Kansas, New Mexico, Nova Scotia, and Saskatchewan.\n\nHope this helps!

I can't give you a sketch, but I can tell you how.\n\nThere are naturally occuring brines (very salty water if you aren't a specialist) which are mainly Potasium Bromide (KBr) in water. \n\nThis is put into the top of a tower and flows downwards over a series of internal plates or trays. \n\nAt the same time, Chlorine gas is sent upwards though the same tower so that the gas (Cl) and the salts (KBr) are in contact. The Cl replaces the Br in the salts and liberates free Bromine. \n\nThe liquid which come out the bottom of the tower is mainly KCl, potasium chloride solution.\n\nYou should find a typical type of tower if you do a search on Contactor Tower or Contactor Column on the web.

Sedimentary rocks can be divided into two major informal groups, referred to as clastics (or siliciclastics) and carbonates. Clastic rocks are formed by erosion of other rocks, igneous, metamorphic and sedimentary. These 'clasts' can be mud, silt, sand, cobbles, or boulders, and are transported by wind, water, or gravity and accumulate where they eventually are buried and pressure and temperature subject them to diagenesis, the process that makes them from unconsolidated clasts to one rock mass. Shale, sandstone, and conglomerate are examples of clastics.\n\nCarbonates can work much differently since they form primarily in the oceans. Many carbonates are made from reefs and other living organisms that grow in the ocean. As these organisms die and leave behind their carbonate skeletons, rocks are formed. Other carbonates are formed from small grains called ooids, small balls that form by precipitating out of sea water, possibly with the help of bacteria or algae. Some ocean algae even form carbonate 'mud' that eventually becomes hard rock. \n\nAnother unusual group of sedimentary rocks are called evaporites. These are rocks like gypsum and rock salt that are deposited by evaporation of water in confined basins. \n\nThe most fascinating part about sedimentary rocks is that they have a past, each one tells a story.

the simplest explanation is as follows:\n\n* igneous rocks are formed when molten lava is erupted on to the earth's surface and cools. i.e. basalt lavas. \n\n* sedimentary rocks are formed when other rocks (possibly igneous, metamorphic or previous sediemtnary rocks) are eroded chemically or physically and are then redeposited. i.e. sandstones and mud stones.\n\n* metamorphic rocks are formed when other rocks (igneous or sedimentary typically) are buried and then exposed to high temperatures and pressures that change the properties of that rock. i.e. marble - metamorphosed limestone.

I will make NaOH from the electrolysis of brine(saturated NaCl solution) using graphite anode and mercury cathode. On electrolysis, sodium will combine with mercury to form sodium amalgam(Na/Hg). Then make that sodium amalgam to combine with water(H20) so that we can get NaOH.

This is just an acid-base reaction.  The nitrogen lone pair acts as a Lewis base and takes the HCl proton.  You then have a quaternary ammonium cation and a chloride anion.  This will form the salt shown as answer b.

Sodium bicarbonate is made in the lab by bubbling CO2 for some time through a concentrated solution in water of sodium hydroxide or sodium carbonate. In the latter case, the reaction takes place more quickly.\n\nCO2 + H2O + Na2CO3 ------> 2NaHCO3\n\nWith sodium hydroxide:\n2NaOH + CO2 -------> Na2CO3 + H2O\nThen:  Na2CO3 + H2O + CO2 -------> 2NaHCO3 \n\nSodium bicarbonate formed is deposited as a white powder and is filtered off, washed 2-3 times with cold distilled water and then left to dry.

you have salty chlorine water.\n\nAs long as the pH is not acidic  -pH drops, then chlorine will leave the solution.\n\n------------------\nIf you mean sodium hypochlorite for chlorine water - salt is a normal decomposition product

you mean into a chloride?\neasy just add concentrated hydrochloric acid.the chloride will precipitate. and the sulfate will come out as hydrogen sulfide gas and water. maybe you need hydrogen to be passed in the mixture.\nna 2(so4)   + hcl  =      nacl   + h2s  + h2o

The major way gold nuggets are formed is by being dissolved in hot water solutions that percolate through rocks. The solubility of gold is enhanced by chloride ions. When this hot water encounters changed conditions (such as cooling or mixing with other water) the gold can exceed its solubility in water and be precipitated. The water circulation about intrusions or extrusions of volcanic rocks often provides the energy to drive this process.\n \nAnother way of concentrating gold into nuggets is by biological activity. Some bacteria are known to be able to concentrate the gold from dilute solutions.

Any acid reacted with any base creates a salt -- that is the definition of a salt.\n\nThe most recognized salt, of course, is table salt -- sodium chloride (NaCl).  This is the product of reacting hydrochloric acid (HCl) with sodium hydroxide (NaOH).  The equation is:\n\nHCl + NaOH ---> NaCl + H2O

You really need to give a little more information about what you are attempting to convert.  However, in very general terms you remove the sulfate, usually by making a solution containing your material basic.  You then form the hydrochloride salt by adjusting the pH back to the acid side via the addition of hydrochloric acid.\n\nPlease note, this process applies to the salt conversion of materials that are basic in nature and water soluable as their salt form.

Think of the net ionic equation which is occuring.\nSince both the HCl and Ca(OH)3 are dissolved in aqueous solution, broken into ions, just focus on the H+ and OH- part of it first.\n\nH+(aq) + OH-(aq) --> H2O(l)\nThe Hydronium ion and the Hydroxide ion react to form water.\nWhat is left over are the Ca+2 and Cl- ion which drop out of the net ionic eqaution since they form the very soluble compound, Calcium Chloride (CaCl2).\n\n2 HCl (aq) + Ca(OH)2 (aq) --> 2 H2O (l) + CaCl2 (aq)

The Halogens are very, very reactive chemicals, and tend to hook up and form salts with the other elements rather than hanging around in a pure elemental form.  They tend to pick up extra charge very well which makes them prime candidates for bonding.
