Question
a) The pH level of a solution is given by pH=−log10[H+]. If the hydrogen ion concentration H+ is0.001 find the pH.
Solution
To find the pH of a solution with a hydrogen ion concentration (H+) of 0.001, we use the formula pH = -log10[H+].
Step 1: Substitute the given H+ concentration into the formula.
pH = -log10[0.001]
Step 2: Calculate the log10 of 0.001.
log10(0.001) = -3
Step 3: Multiply the result by -1 to find the pH.
pH = -(-3) = 3
So, the pH of the solution is 3.
