I have a solution that has a pH of 4. i am adding 100,000x more [OH-] ions. what is my new pH? what color will litmus be in the new solution?

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.

Which factor is likely to impact the possible number of compounds ?

Which of the following is not an assumption that scientists must make about the natural world? a. regularity b. causality c. predictability d. plausibility
