Standard solutions are solutions that resist changes in pH when small amounts of acid or base are added to it. Acidic standard solutions are simply those with a pH of less than 7. They are usually made from a weak acid and one of its corresponding salts.
Alkaline standard solutions: An alkaline standard solution has a pH greater than 7. They are made from a weak base and one of its corresponding salts.
