a chemistry student needs to standardize a fresh solution of sodium hydroxide. she carefully weighs out 87. mg of oxalic acid (h,c,o), a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250. ml of distilled water. the student then titrates the oxalic acid solution with her sodium hydroxide solution. when the titration reaches the equivalence point, the student finds she has used 52.7 ml of sodium hydroxide solution. Determine the coefficient of determination.
Based on your answer to number 6, above, discuss the adequacy of the regression model. Determine the standard error of the estimate. Interpret its meaning.
