a) write out the acid dissociation reaction for hydrochloric acid. b) calculate the pH of a solution of 5.0 x 10^-4 M HCl. c) write out the acid dissociation reaction for sodium hydroxide. d) calculate the pH of a solution of 7.0 x 10^-5 M NaOH.
Calculate the pH of 0.300 L of a 0.500 M NaHSO3 / 0.300 M Na2SO3 buffer before and after the addition of the following solutions. Assume that the volume remains constant.
Draw the product of the following reactions and indicate whether the product would be (R), (S), racemic, or achiral. You do not have to draw a projection that shows the configuration; you can just use the label
a 5.00L air sample at a temperature of -50 degrees celsius has a pressure of 107 kpa. what will be the new pressure if the temperature is raised to 102 degrees celsius and the volume expands to 7.00L.
The equilibrium constant KC for the reaction 2H2(g) + CO(g) ? CH3OH(g) is 135 at a certain temperature. If there are 5.23 ? 10?2 moles of H2 and 3.73 ? 10?
A piece of sodium metal reacts completely with water as follows. 2 Na(s) + 2 H2O(l) 2 NaOH(aq) + H2(g) The hydrogen gas generated is collected over water
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.
Calculate the pH of the buffer that is produced when 5.00 grams of boric acid (HBH2O3 molecular weight =61.84g/mol, Ka = 5.83x10-10) is added to 250. ml of 0.100 M NaOH.
