Describe a solution with a pH of 9?

Answer 1

This solution is basic, since it has very little dissolved Hydronium ion. (It has exactly 10-9 hydronium ions per Liter, which is very few. Less hydronium ions means less acidity.)

Remember too that a solution with pH > 7 is basic, and a pH < 7 is acidic.

Remember that pH is a number that represents the concentration of hydronium ion (H+) in a solution. The equation for this is

pH = -log10[H+].

If you have a pH of 9, then you can solve for the concentration of hydronium ions as follows.

pH = 9

-9 = log10[H+]

You can then raise both sides of the equation to the power of 10 in order to eliminate the log.

10-9=10log10[H+]

10-9=[H+] since 10log10[H+] = [H+]

So a pH of 9 indicates a hydronium ion concentration of [H+] = 10-9

Answer 2

A base. Any solution with a hydronium ion concentration of 10-9 mol/l has a pH of 9, the hydroxide ion concentration is 10-5. pKw is 10-14

Answer 3

A solution with pH = 9 is an alkaline solution.

Answer 4

The lower on the scale, the more acid. The higher on the scale, the more alkaline. A pH of 7 is neutral. That makes a pH of 9 an alkaline.

Answer 5

Basic or alkaline. A pH above 7 is basic while one below 7 is acidic.

Answer 6

the weak bases have pH=8 or 9 as the carbonates and bicarbonates the common substances in this range are washing soda , baking soda , soap, lime water and milk.

Answer 7

hand soap

Answer 8

Hand soap

Answer 9

acid
