Do organic acids possess mobile charge carriers when dissolved in water?
yes
Why does protein exist as a zwitterion?
Because proteins are made up of amino acids and amino acids have both an NH2 group and a COOH group. Amino acids are zwitterions because the NH2 group protonates and the COOH group deprotonates, giving a molecule where one part has a positive charge and another has a negative charge.
Do bases and acids conduct electricity?
Yes, they both have a charge and therefore both can conduct electricity.
How do you determine if a compound is electrolyte or nonelectrolyte?
Electrolytes: acids, bases, and salts (ionic compounds) Nonelectrolytes: usually covalent compounds with the exception of acids. Ionic compounds : One of the ions has a positive charge (called a "cation") and the other has a negative charge ("anion") *Electrolytes can be strong or weak
What functional group contributes negative charge?
anything with lone pairs, or things like alcohols and carboxyllic acids
What type of net charge do most proteins carbohydrates and nucleic acids have?
negative charge
What charge to hydrophobic amino acids have at pH6?
natural
What kind of charge does protein have?
Proteins do have charges based on its amino acid content. there are polar uncharged and acidic, basic amino acids exist in the cells(Lysine, Arginine, asparic acid are a few charged groups). Based on the codes of mRNA proteins are formed by these amino acids in a sequence.

Why amino acids exists as zwiter ion?
It is an ion with overall neutral charge.But in its chain , there exists two parts where one part has a negative charge and another side has an equal positive charge to nullify the negative charge. This ion becomes positively charged in acidic medium and negatively chargedin alkaline medium. Eg amino acids etc.
What functional group contributes negative charge?
anything with lone pairs, or things like alcohols and carboxyllic acids
Which of the amino acids would whne incorporated into polypeptide chain make the charge of the polypeptide more positive?
Arginine
Why are acids solutions electrolytes?
They dissociate in solutions producing free ions. These charged particles can carry an electric charge.
Why are acids and bases concidered electrolytes?
An acid has to have a positive charge on a atom or molecule delivering the acid, Therefore any atom with a charge is an ion and it is a electrolyte because any solution that has free ion is determine as an electrolyte.
