1) Calculate of pH of each of the following strong acidsolutions: (a) 8.5 x 10^-3 M HBr, (b) 1.52 g of HNO3 in 575 mL ofsolution, (c) 5.00 mL of 0.250 M HClO4 diluted to 50.0 mL, (d) asolution formed by mixing 10.0 mL of 0.100 M HBr with 20.0 mL of0.200 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 MNaOH diluted to 2.00 L, (d) a solution formed by adding 5.00 mL of0.105 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 Msolution 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.
