Post Laboratory Sheet: . In this procedure it is important to store the sodium hydroxide, NaOH, solution securely capped to avoid evaporation of water. a. What would the impact of leaving the plastic bottle of sodium hydroxide open to the atmosphere and allowing some of the water to evaporate be on the concentration of the solution. Would the concentration be higher, lower, or unchanged. Provide an explanation for your answer. b. If the sodium hydroxide, NaOH, solution was not re-standardized after some of the water evaporated, what impact would this have on the quantity of sodium hydroxide solution needed to reach the endpoint for a given mass of acid? Would the quantity be higher, lower, or unchanged. Provide an explanation for your tablet usin tration method. answer. c. If the sodium hydroxide, NaOH, solution was not re-standardized after some of the water evaporated, what impact would this have on the value of the acid molar mass calculated? Would the value be higher, lower, or unchanged. Provide an explanation for your answer. Chemical background
