Question

a ph of a solution is 4.if we decrease its strength by 1000times what will be its ph .​

Answer 1

If the pH of a solution is less than 7, the solution is called acidic; if the pH is about 7, the solution is neutral; if the pH is greater than 7, the solution is is called basic. In an acidic solution, then, the concentration of hydrogen ions is greater than the concentration of hydroxide ions.
