Latihan Soal Hidrolisis garam II Kimia Kelas XI

Salt Hydrolysis Practice Questions II Chemistry Class XI Explains how to determine the pH of a salt solution undergoing hydrolysis and the amount of salt needed to obtain the desired pH. The explanations are clear and concise, so students do not need to memorize the necessary formulas. ................................................................................................................................................................................... 1. A 0.2 M H2CO3 solution with a volume of 100 mL was mixed with 100 mL of a 0.2 M Ca(OH)2 solution. Determine the pH of the mixed solution if the Ka value of H2CO3 is 4 x 10-7! 2. A total of 100 mL of H2SO4 solution reacted completely with 100 mL of NH4OH solution to form a salt solution with a pH of 6. If the Kb of NH3 is 2 x 10-5, determine the concentrations of each of the H2SO4 and NH4OH solutions used! 3. A total of 18.24 grams of Mg(CN)2 salt was dissolved in 2 L of water to produce a salt solution. Determine the pH of the salt solution if Ar Mg = 24, N = 14, and C = 12! (Ka HCN = 6 x 10-10) 4. 1 L of CaC2O4 (Ka H2C2O4 = 6 x 10-2) has a pH of 8. Determine the mass of CaC2O4 in solution if Ar Ca = 40, O = 16, and C = 12!
