If 0.1 M acetic acid has a pH of 2.87, what is the concentration of H+ ions?

If 0.1 M acetic acid has a pH of 2.87, what is the concentration of H+ ions?

Step 1: Understand that pH is a measure of how acidic or basic a solution is.
Step 2: Recall the formula that relates pH to the concentration of hydrogen ions (H+): [H+] = 10^(-pH).
Step 3: Identify the given pH value, which is 2.87.
Step 4: Substitute the pH value into the formula: [H+] = 10^(-2.87).
Step 5: Calculate 10 raised to the power of -2.87 using a calculator or logarithm table.
Step 6: The result of the calculation will give you the concentration of H+ ions, which is approximately 0.001 M.

pH and Hydrogen Ion Concentration – The relationship between pH and the concentration of hydrogen ions (H+) in a solution, where pH is calculated as the negative logarithm of the H+ concentration.
