Answer the following questions in a clear and concise manner. If calculations are needed to answer question, please show all work including units, sig figs and chemical formula/symbols where appropriate.
1. Write the pH you got for the following solution in the lab, Tap water: pH = ___________ , 1.0M HCl solution, pH = _________ . Circle the one that has a higher [H+] (hydronium ion Molarity/concentration)
2. Write the pH you got for the following solution in this lab, 1.0M NaOH. pH = ______ and 1.0M ammonia water (actually NH4OH) pH = ___________
In the space below explain why they do not have the same pH even though they have the same Molarity (both 1.0M solutions).
3.
4.
5. Please provide in the blanks below, the observations you obtained from one of the solutions in the lab.
