The following statement is wrong :
"Sodium hydrogensulphate is formed from mixing a strong acid with strong alkali, so it is neutral."

Actually, the final solution of mixing a strong acid with a strong alkali is neutral ONLY WHEN both the strong acid and the strong alkali are JUST COMPLETELY REACTED. However, in forming sodium hydrosulphate, the sulphuric acid is NOT COMPLETELY REACTED.
