An empty flask is found to have a mass of 97.34 grams. a sample of vinegar is added to the flask and the total mass is measured at 119.22 grams. a 5.023-gram sample of tartaric acid is dissolved in water and diluted to 250.0 ml in a volumetric flask. a 34.2 ml portion of this tartaric acid solution reacts completely with 28.3 ml of a sodium hydroxide solution. the vinegar sample requires 40.1 ml of this same sodium hydroxide solution for complete reaction. calculate the percent (w/w) of acetic acid in the vinegar.

Magnesium hydroxide, mg(oh)2, is used in several antacid formulations. when it is added to water it dissociates into magnesium and hydroxide ions. mg(oh)2(s) < --> mg2+(aq) + 2oh-(aq) the equilibrium constant at 25°c is 8.9 x 10-12. one hundred grams of mg(oh)2 is added to 1.00 l of water and equilibrium is established. what happens to the solution if another 10 grams of mg(oh)2 are now added to the mixture? a. the hydroxide ion concentration will decrease. b. the hydroxide ion concentration will increase. c. the hydroxide ion concentration will be unchanged. d. the solution will become supersaturated. e. none of the above conclusions is justified without additional information.
