Calculate the pH of each of the solutions and the change in pH to 0.01 pH units caused by adding 10.0 mL of 3.48 M HCl to 350 mL of each of the following solutions:
a) water
b) 0.117 M C2H3O2^1-
c) 0.117 M HC2H3O2
d) a buffer solution that is 0.117 M in each C2H3O261- and HC2H3O2
The atmospheric pressure in La Grande (683 atmospheric pressure) is significantly lower than that of Portland (760 normal pressure). How would the boiling points of a liquid compare in these two locations? Why?
A 3.00 g sample of a salt dissolves in 9.10 g of water to give a saturated solution at 25°C. What is the solubility (in g salt/100 g of H2O) of the salt?
