1. What is the molar concentration of a nitric acid solution if 25.0 mL of the acid neutralizes 40.0 mL of a 0.50 mol/L solution of potassium hydroxide?
2. Your teacher has prepared 100 mL of 1.5 x 10-3M hydrochloric acid. What is the pH, pOH and [OH-] of the solution? Is the solution acidic, basic or neutral?
Estimate the magnitude of the absolute error nad percent error in the measured sample volumes compare those errors to the erors that occur when measuring volumes of approimatley 8 ml as normally done in this experiment.
What would happen if the buret washed and rinsed properly but not conditioned with sodium hydroxide solution, prior to standardizing the sodium hydroxide solution?
A flask contains 300mL of 0.12M phosphate buffer that has a pH of 7.2. What volume of 0.2M HCl should be added to drop the pH to 6.7
Magnesium hydroxide 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).
A solution is prepared by dissolving 179 g sucrose (C12H22O11) in enough water to produce 1.15 L solution. What is the molarity of this solution?
