Are the following solutions acidic, basic, ot neutral.
1. [h3o+] = 2.5 x 10-9 m
2. [oh-] = 1.6 x 10 -2 m
3. [h3o+] = 7.9 x 10-3 m

1) Basic

2) Basic

3) Acidic

Explanation:

pH of a solution is a measure of the H3O+ ions in the solution and hence reflects its acidity.

Solutions are classified as acidic, basic or neutral based on the pH range

-pH < 7, acidic

- pH = 7, neutral

- pH > 7, basic

1) [H3O+] = 2.5*10^-9M

Since pH > 7, solution is basic

2)[OH-] = 1.6*10^-2M

pH = 14 - pOH = 14 - 1.80 =12.2

Since pH > 7, solution is basic

3) [H3O+] = 7.9*10^-3M

Since pH < 7, solution is acidic

sure im new too!
