1) Calculate of pH of each of the following strong acid solutions:
(a) 8.5 x 10-3 M HBr
(b) 1.52 g of HNO3 in 575 mL of solution
(c) 5.00 mL of 0.250 M HClO4 diluted to 50.0 mL
(d) a solution formed by mixing 10.0 mL of 0.100 M HBr with 20.0 mL of 0.200 M HCl.
2) Calculate [OH-] and pH for
(a) 1.5 x 10-3 M Sr(OH)2
(b) 2.250 g of LiOH in 250.0 mL of solution
(c) 1.00 mL of 0.175 M NaOH diluted to 2.00 L,
(d) a solution formed by adding 5.00 mL of 0.105 M KOH to 15.0 mL of 9.5 x 10-2 M Ca(OH)2
3) Latic acid (CH3CH(OH)COOH) has one acidic hydrogen. A 0.10 M solution of lactic acid has a pH of 2.44. Calculate Ka.
4) A 0.100 M solution of chloroacetic acid (ClCH2COOH) is 11.0% ionized. Using this information, calculate [ClCH2COO-], [H+], [ClCH2COOH], and Ka for chloroancetic acid.
