On a separate sheet of paper, write equations for
these neutralization reactions.
1. Hydrochloric acid and potassium hydroxide
produce potassium chloride and water.
2. Sulfuric acid and barium hydroxide produce
barium sulfate and water.
3. Phosphoric acid and sodium hydroxide
produce sodium phosphate and water.

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
