This lab will consists of two parts as follows:
a) Each group will make one of the solutions below and place around 20.ml into a 100.ml beaker and label it with Molarity and solution's chemical formula.
b) Each group will determine the pH with a) pH paper (record pH to the tenth place) and b) LabQuest2 pH probe of each of the 4 solutions.
c) Each group will also determine the color change on the red and blue litmus paper.
c) Each group will then calculate (in their lab book) the theoretical pH of each solution. Show all work as if calculations are part of a test.
The solutions to be made are (any leftover solution will be put into plastic containers with label of molarity and chemical formula):
a) 1.0M HCl solution, 500ml of this solution (from a 6.0M solution)
b) 1.0M HC2H3O2 solution, 500.ml of this solution (from a 6.0M solution)
c) 1.0M NaOH solution, 250.ml of this solution (from a 2.0ml solution).
d) 1.0M NH4OH solution (it is called ammonium hydroxide but the other name is ammonia water solution), 250.ml of this solution (from a 2.0ml solution)
Please show your calculations on making "your" solution. Show all work as if it was a problem on a test. Share with other groups so everybody have the calculations needed to make the 4 solutions (these calculations will be part of your lab write-up.)
