If 0.45 M of ammonia solution has a pH of 9.20, what is the H+ concentration of the solution?
pH = -log(H^+)
9.2 = -log(H^+)
-9.20 = log(H^+)
To determine the H+ concentration of the ammonia solution, you can use the relationship between pH and H+ concentration.
The pH is a measure of the acidity or alkalinity of a solution and is defined as the negative logarithm (base 10) of the H+ concentration. Mathematically, it is expressed as:
pH = -log[H+]
To find the H+ concentration, you can rearrange the equation:
[H+] = 10^(-pH)
In your case, the pH is given as 9.20. Plugging this value into the equation:
[H+] = 10^(-9.20)
Calculating the value using a scientific calculator or computer software, you'll find that the H+ concentration is approximately 0.00000000079 M.
Therefore, the H+ concentration of the ammonia solution is approximately 0.00000000079 M.
