What kind of ion is contained in salts that produce an acidic solution? a positive ion that attracts a proton from water a negative ion that releases a proton to water a positive ion that releases a proton to water a negative ion that attracts a proton from water?

a negative ion that attracts a proton from water is the correct answer.

Explanation:

An acidic solution is defined as a solution that is formed when a strong acid combines with a weak base.

For example,

So, when from attract a proton from water then it will form HCl which is acidic in nature and being a strong acid will result in an acidic solution.

When a solution is formed from a strong bases and weak acid then it will result in a basic solution. When a weak acid will react with a weak base then it will result in a neutral solution.

Hence, we can conclude that a negative ion that attracts a proton from water is the kind of ion that is contained in salts that produce an acidic solution.
