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)

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
