1. what type of acid is used in automobile batteries? how does this acid cause a battery to work?
2. describe how acids and bases work in our bodies. list two examples of acids and bases in nature. describe the harmful effects of acid rain.
3. what substance is neither an acid nor a base? how does it stay neutral?
4. which ion concentration does the ph scale measure?
5. how long is the scale?
6. the higher the hydrogen ion concentration, the the ph. the lower the hydrogen ion concentration, the the ph. a ph of is considered neutral. acids have values below this number. bases have values above this number.
7. what is the litmus paper? how is it used to determine if a compound is an acid or base?
8. a universal indicator can be used to determine the exact ph. what other devices can determine an accurate measurement?

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.
