Answer:
The answer is 1.778*10^-9
Explanation:
Using the formula
pH = -log[H^+]
Since the pH of the solution has been given to be 8.75,
Therefore,
8.75= -log [H^+]
Let's take H^+ to be x
8.75= -log x
Let's look for x, since the log is in base 10
X = 10^-8.75
X = 1.778 * 10^ -9
Therefore, H^+ =1.778 *10^-9
