Calculate the pH for the following weak acids
.01M Formic acid (HCHO2) aka= 1.7 x 10^-4

pH = 2.88

Explanation:

For a weak acid solution, the pH can be calculated using the following formulas:

Where Ka = and C is the molar concentration.

We are given Ka and C by the problem, meaning we can now proceed to calculate [H⁺]:

Finally we calculate the pH:

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.
