What is the pH of a 1.0 x 10-4 M solution

4

Explanation:

pH is the negative logarithm of hydrogen ion concentration in a solution. pH can be mathematically expressed as;

pH = -log(H+)

where H+ is the hydrogen ion concentration.

pH = -log(1.0 x 10-4 M)

pH = -(-4)

pH = 4 (The two minus signs cancelled out, so, the result becomes 4)

Thus, the pH of the solution is 4 (indicating an acidic solution)

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
