Phthalic acid (H 2 C 8 H 4 O 4 , abbreviated H 2 Ph ) is a diproticacid. Its ionization in water at 25°C takes place in twosteps: H 2 Ph ( a q ) + H 20 (1)2H 30+ ( a q ) + HPh – ( a q) Ка1-1.26 х 10- 3Н2 Ph - (аq)+H20(1) нзо+(аq) + Ph 2 - (aq) If 0.0100 mol of phthalic acid is dissolved per liter ofwater, calculate the equilibriumconcentrations of H 2 Ph , H P h-, Ph Ка 2-3.10х 10 - 6 2 -, and H 30 +.

Ammonia (NH3) is a colorless gas with a pungent smell and is quite soluble in water. The Henry's Law constant for NH3 is KH = 62 M/atm at 298K and the ambient concentration of NH3 is fixed at 0.2 ppm. Solve for [NH4*] and [OH] in the solution. What is the pH of the solution?

The pH scale depends on the value of Kw. What would the pH of neutral water be if the Kw was 5.54 x10-15? IMPORTANT: When entering your answer: •Enter the number only (no units) • Do not leave any spaces Use a leading zero before the decimal when necessary Report your number to 3 decimal places (regardless of the significant figures) • Correctly round your answer to the 3rd decimal place (allowed margin of error is only ± 0.001, so always use un- rounded numbers in your calculations) Examples: 0.123 or 9.876
