Draw the pH scale of the following non-aqueous solvents.
Describe the chemical characteristics of amphiprotic and aprotic solvents.
1. Calculate the pH of the following solutions:
A. 0.01 M NaOH
B. 1.0 x 10-8 M HCl
An isotonic saline solution was prepared by dissolving 0.92g of NaClin
2 points
enough distilled water to make 100ml solution. What is the percent by
mass/volume of the solution?
