How many moles of sulfate ions are there in a 0.20 L solution of 0.080 molar aluminum sulfate?
Determine the molar mass of carbon dioxide by measuring the mass of an Erlenmeyer flask full of the gas. The following calculations are intended to familiarize you with the general procedure:
2 components mixture give the tlc shown when 1:1 mixture of hexanes:ethyl acetate is used as the developing solvent which components is more polar and how can you tell?
balance the equation when 1-butanol is added to acetic acid.....then 1 drop of conc. sulfuric acid is added, and then 2 mL of water.
What is the pH of a solution that is 0.75 M in sodium acetate and 0.50M in acetic acid? (Ka for acetic acid is 1.85 x 10-5).
What volume of .250 M NaOH is required to neutralize a 10mL sample of .750 M HCl.
0.25 g of hydrogen chloride HCl is dissolved in water to make 8.0 L of solution. What is the pH of the resulting hydrochloric acid solution?
a 1.00 liter solution contains 1.00 mol of weak acid HX. After 0.60 mol of Oh- is added to this olution, the pH of the solution is 4.00. Calculate the Ka for the acid HX.

What is the final temperature of the water and pieces of metal?
The sucrose solution used in the fermentation was 0.350 M. Assume solubility of CO2 in water equivalent to the solubility in the sucrose solution. Hint: some of the CO2 obtained from the fermentation dissolves in the solution, the rest goes to the..
As pH increases, hydronium ion concentration increases. As pH increases, hydroxide ion concentration increases
