A saturated solution of metal (II) hydroxide, M(OH)2, has a =4.84 x 10-3 Determine the value of the Ksp for M(OH)2.

Determine which of the following statements are True or False about 500.0 mL of buffer consisting of 0.70 M butanoic acid (HC4H7O2) and 0.85 M sodium butanoate (NaC4H7O2): The pH slightly increases when 25.0 mL of 0.25 M sodium hydroxide is added to the buffer but the buffer is still effective 0.150 moles of hydrochloric acid will be neutralized by butanoic acid and the buffer will still be effective 0.220 moles of sodium hydroxide will be neutralized by butanoic acid and the buffer will still be effective

Consider a saturated solution of MCl3 with a molar solubility of 0.18 M. What do you expect to see when you add 0.1 M NaCl to the solution (assume that there is no change in volume) The reaction will shift left The reaction will shift right The reaction will not be affected As a result of which The molar solubility will increase The molar solubility will decrease The molar solubility will remain unchanged
