The pH scale is used to specify the acidity or basicity of an aqueous solution.
1. A solution with a pH of 7 is considered .
2. As the concentration of H+ ions increases, the pH value .
3. The sum of pH and pOH for any aqueous solution at 25°C is always .

1. Calculate the pH of a 0.001 M HCl solution. Is it acidic, basic, or neutral?
2. A solution has a [OH-] concentration of 1.0 x 10^-4 M. Calculate its pOH and pH.
3. If the pH of a solution is 8.5, what is its [H+] concentration?
1. A solution with a pOH of 12 is highly acidic.
True

2. Pure water at 25°C has a pH of 7 and a pOH of 7.
True
False
1. Explain the relationship between the concentration of hydrogen ions ([H+]), hydroxide ions ([OH-]), pH, and pOH in an aqueous solution. How do these values change when a solution becomes more acidic or more basic?
