charged acid

Postby Kellylin_4D » Mon Dec 02, 2019 3:35 pm

What does it mean when the acid is neutral or negatively charged? Where does this charge come from? How can I tell whether it's charged or not? Do bases get charged as well?

Whether the acid is neutral or negatively charged depends on if it is protonated or not. For example, HCl is a strong acid. In this form, it is considered neutral because it does not have a positive or negative charge associated with it. However, when HCl is deprotonated and separated into H+ and Cl- in aqueous solution, the Cl- is negatively charged. Remember that the general form of a neutral acid is HA, where H is the proton and A is the acidic anion. When the acid dissociates in water, it separates into the proton and acidic anion forms, where the acid is considered to have a negative charge (anion is negatively charged). When determining charge, consider whether the acid is a neutral molecule or if it is has been ionized, in which case it will have a negative charge.
