Asample of lake water at 25°c is analyzed and the following parameters are found: total alkalinity = 6.2 x 10-4 m phenolphthalein alkalinity = 1.0 x 10pm ph = 7.6 hardness = 30.0 mg/l [mg²+] = 1.0 x 10-4 m extract all possible single-ion concentrations that you can by combining one or more of these data. also determine whether or not the water is at equi- librium with respect to the carbonate-bicarbonate system and whether or not it is saturated with calcium carbonate.

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
