If pH = 6.6, calculate the molar concentration of H^ + (aq) in the solution.
pH = -log(H^+)
If ions O^2- are added to water, what reaction, if any, occurs?
if 0.80g of magnesium react with 40.0s calculate the reaction rate
To calculate the molar concentration of H^+ (aq), we can use the formula for pH.
pH is defined as the negative logarithm (base 10) of the molar concentration of H^+ ions in a solution.
The formula to convert from pH to H^+ concentration is:
[H^+] = 10^(-pH)
Substituting the given pH value of 6.6 into the formula:
[H^+] = 10^(-6.6)
Calculating this using a calculator:
[H^+] ≈ 2.51 x 10^(-7) M
Therefore, the molar concentration of H^+ (aq) in the solution is approximately 2.51 x 10^(-7) M.
