Electrophoresis is a process of seperation of molecules based on electric charge they possess using mild electric field in an electrolyte medium. Protein peptides for eg. can be separated by breaking the long protein chain using denaturing chemical such as beta-mercaptoethanol and treated with a detergent such as sodium dodycyl sulphate to render net negative charge to the molecules (peptides so broken). Now, sepration takesplace mainly on the basis of molecular weight of the peptide. U can use standard peptides/proteins to get a separation calibration curve. These are available commercially.

liquid chromatography  separates by charge at a given pH\ngel chromatography  separates by size\n\nthen there is electrophoresis\n\nNow would be a good time to point out I failed one biochemistry exam 4 times\n\ngood luck.

When an atom or molecule has the same number of protons and electrons, it is considered neutral.  If it loses electrons (which have negative charge), the particle becomes positively charged.  If it gains electrons, the particle becomes negatively charged.

There are two acidic protons on H2SO4, so normality is 2*molarity.\nanswer is 0.3 N

this is because saliva contain lysozyme.

18F\nFluorin has 9 protons(9+)and 9 electrons(9-).Therefore,there'll be no charge since positive charges from 9 protons were neutralize by negative charges of 9 electrons.+9-9=0..It is known as atom because it doesn't carry any charge.If it is ion,the amount of electron will more than proton,or the other way round.\n\nHope this will help!!=)All the best!!

Polar molecules, such as water molecules, have a weak, partial negative charge at one region of the molecule (the oxygen atom in water) and a partial positive charge elsewhere (the hydrogen atoms in water). \n\nThus when water molecules are close together, their positive and negative regions are attracted to the oppositely-charged regions of nearby molecules. The force of attraction is called a hydrogen bond.

Actually, if you mean strength as in acidity, a solution with a pH of 5 would be 10 times stronger than one with a pH of 6.\n\nHowever, both would be very weak acids, since neutral is about pH 7.

C, having both positive and negative charges on one molecule.

One property of matter is the electric charge. Most sub-atomic particles have either a positive (+) or negative (-) electrical charge. Those that don't are considered neutral. The most common charged particles are the electron and proton. Atoms with an excess of electrons are called negative ions. Those with missing electrons are called positive ions. There is an electrical field that flows between opposite charges, causing an electrical force. This results in an attractive force between the opposite charges and a repelling force between like charges.

The Answer is quite simple. Isotonic solutions are defined as two or more solutions having the same solute concentrations.

let me explain this with an example.take Cl atom which has 17 protons in the nucleus and equal no. of electrons(17)revolving around the nucleus.this means tht the 17 positive charges are attracting the 17 negative charges.\nnow let us consider the chloride ion Cl(-1). the protons are again 17 here but one negative charge is extra ie there are 18 electrons.so,in this case the 17 positive charges are pulling the 18 negative charges.\nnow u can imagine in which case is the pull less efficient atom or anion?\nobviously it is less efficient in case of anion because of the inequality of charges thus making it bigger in size.\nhope ,i ve made it clear with an example...

The ethoxide ion. By the positive inductive effect, the alkyl group releases electrons to the O- portion of the ion. Remembering that bases are proton acceptors, it is easy to see that the greater negative charge will make it easier to accept the proton.

Hydrogens in water have a small positive charge, and oxygen molecules have a small negative charge...this is due to the higher electronegativity of oxygen compared to hydrogen...\n\nThis results in attraction of the positive and negative charges of different water molecules, resulting in what is called hydrogen bonds

A solution with the same ionic concentration as a cell.  For example, PBS is a isotonic solution with respect to human cells.  Hypertonic is higher ionic concentration, hypotonic is lower ionic concentration.  hyptonic solns will lyse cells because of osmosis, water flows into the cells while solutes flow out of the cell, to reach equilibrium.  Thus cells will lyse in water without signficant amts of solvents.

damn! i should know this...i'm a science chem/bio student\n\ngimme some time...they are basic and acidic in nature. so in solution, there's the [H] ions for reaction in/around cells
