Questions & Step-by-Step Solutions
If 0.1 M acetic acid (CH3COOH) is 1% ionized, what is the concentration of H+ ions?
Step 1: Understand that 0.1 M acetic acid means there are 0.1 moles of acetic acid in 1 liter of solution.
Step 2: Know that 1% ionized means that 1% of the acetic acid molecules have turned into ions.
Step 3: Calculate 1% of 0.1 M. To do this, multiply 0.1 M by 0.01 (which is 1%).
Step 4: Perform the calculation: 0.1 M * 0.01 = 0.001 M.
Step 5: The result, 0.001 M, is the concentration of H+ ions in the solution.
