A1 forms when an acid is neutralized by a base. 1. salts can be neutral, or in solutions. salts of 2. strong acid–strong base reactions produce solutions with 3. water. salts formed from the neutralization of weak acids or weak 4. bases water. they produce solutions that are acidic or . basic. for example, the ph of a solution at the equivalence point is . greater than for a acid titration. solutions that resist changes in ph are called solutions. the buffer is the amount of acid or base that can be added to a buffer without changing the ph greatly.
