Electrolytes and Molarity
Iii)salt is added to 81.4 g of water?
iv) Identify the electrolytes and the non-electrolytes among the following compounds:
(1) ethyl alcohol, C2H5OH
(2) potassium sulfate, K2SO4
(3) sodium bromide, NaBr
(4) methyl alcohol, CH3OH
(5) lithium chloride, LiCl
v) In a clean 250-mL volumetric flask, 125 mL of a 6.0 M hydrochloric acid was added. This was then diluted with more water to reach the 250-mL mark. What is the molarity of the acid at this time?
vi) Calculate the pH of 0.10 M HCl solution
vii) Calculate the final concentration if 4.0 L of 1.5 M NaCl and 2.0 L of 3.0 M NaCl are mixed.
