The ?a value for acetic acid, CH3COOH(aq), is 1.8×10−5. Calculate the pH of a 2.40 M acetic acid solution. Calculate the pH of the resulting solution when 2.50 mL of the 2.40 M acetic acid is diluted to make a 250.0 mL solution.

What is the pH of a 3.47 x 10 ^-4 M solution of hydrochloric acid?

The pH of a basic solution is 9.77. What is [OH⁻]?

What is the pH of a 8.5 × 10⁻⁶ M HBr solution?

Los Angeles has water regulations that requires any wastewater poured down the drain to be between pH = 4.5 and pH = 9.0. In lab, Dr. Smith is feeling lazy and decides to pour waste down the drain instead of going through the appropriate procedure for disposal of chemical waste. The waste contained your 0.250 M solution of HCl. Does this wastewater comply with the Los Angeles water standards?   Hint: Recall that strong acids completely dissociate.  HCl → H+ + Cl- How is [H+] related to the concentration of the HCl solution? a)No, this solution has pH below the safe range. b)Yes, this solution has pH within the safe range. c)No, this solution has pH above the safe range. d)The pH will depend on the volume (liters) of solution.
