Yes. Some alkalis do have a pH above 9. e.g. 46% NaOH solution.

Is pH of soap 4 or 9?

True soap (fats reacted with lye) is slightly alkaline. A pH of 4 is acid, a pH of 9 is alkaline. You can probably figure it out now. However many "soaps" on the market are really detergents, which tend to be closer to neutral (pH 7).


Why glass electrode cannot be used for solution of Ph above 9?

This is because of alkaline error above pH of 9. Alkaline Error is a systematic error that occurs when glass electrodes are used to read the pH of an extremely alkaline solution (pH above 9); the electrode responds to sodium ions as though they were hydrogen ions, giving a pH reading that is consistently too low. However it is now possible to purchase [H electrodes made from special glass that can be used above pH 9.


The compound with a pH of 9 is alkaline and is?

likely a base. It will have a higher concentration of hydroxide ions (OH-) compared to hydronium ions (H+), contributing to its alkaline pH.
