a. A 250.0ml of a solution of the strong base, CsOH(MW = 150.0 g/mole) is made. The pH is measured to be 8.90. What mass of cesium hydroxide is present in the solution?
b. The surface of Venus is quite inhospitable with an average temperature of 450 ̊C and a pressure of 92 atm (earth). Under these delightful conditions, the pKw of water is estimated to be 24. What is the pH of neutral water on Venus?
c. An aqueous acetic acid (HOAc) solution is 1.00 % dissociated. What will the concentration of H3O+ be if 0.82 g of sodium acetate (NaO2C2H3) is added to 100.mL of solution?
d. PICTURE ATTACHED Glutaric Acid is a diprotic organic acid with a molecular formula of H2C5H6O4, and a molecular weight of 132.12 g/mol. The stepwise acid dissociation reactions and the Ka values are given below. An aqueous solution is prepared by dissolving 1.02 g of glutaric acid in water to form 500.0 ml of solution. Calculate the pH, [H2C5H6O4], [HC5H6O4–], and[C5H6O42–] after the solution has reached equilibrium.
