Q
Q: What is the concentration of H+ ions in a solution with pH 4?
Solution:
[H+] = 10^(-pH) = 10^(-4) = 0.0001 M.
Steps: 5
Show Steps
Step 1: Understand that pH is a measure of the concentration of hydrogen ions (H+) in a solution.
Step 2: Recall the formula to find the concentration of H+ ions from pH: [H+] = 10^(-pH).
Step 3: Substitute the given pH value (which is 4) into the formula: [H+] = 10^(-4).
Step 4: Calculate 10 raised to the power of -4, which equals 0.0001.
Step 5: Conclude that the concentration of H+ ions in the solution is 0.0001 M.
