Why do sds coated polypeptides serperate in a gel, when placed in an electrical field?

Explanation: SDS coated polypeptide separate in a gel when placed in an electric field, because SDS coated proteins are negatively charged while the electric field is politely charged. this will cause the proteins to move. the proteins that will move farthest is the smaller ones because it is easier to migrate through the gel.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
