Need help, not sure how to get started with this problem. An acidic solution has a pH of 4.2. If 10.0 mL of this solution is diluted to final volume of 1.00 L, what is the pH of the resulting solution?
diluted by a factor of 1000/10=100 times.
that means 1 part original stock,99 parts water.
so, a dilution of 100 times means a change in pH of log scale, or 2 (ie, 10^2 is 1OO.,
original pH: 2.2
