Compared with a basic solution at ph 9

WebHighly basic. Solutions with a pH of greater than 13 are highly basic. They show blue/purple to universal indicator and blue to litmus. Highly basic solutions include sodium hydroxide(aq), potassium hydroxide(aq) and barium hydroxide(aq). Such solutions are often said to be 'caustic'. For example 'caustic soda' is an old term for sodium hydroxide. WebpH = −log [H+] pH is usually (but not always) between 0 and 14. Knowing the dependence of pH on [H + ], we can summarize as follows: If pH < 7, then the solution is acidic. If pH = 7, then the solution is neutral. If pH > 7, then the solution is …
