A "little more" than 5 mL of a saturated solution of borax is transferred to the corresponding calibrated test tube and subsequently titrated with the standardized hydrochloric acid solution. How will this "generosity" affect the reported molar solubility of borax for that sample.... too high, too low or unaffected? Explain.
what is the resulting total pressure of gases in the now-joined flasks? (assume no reaction between the gases and that the gases behave ideally)
