Hypochlorite ion comes from bleach, where it is found as sodium hypochlorite. Concentration of NaOCL is either 6% or 6.15%. Calculate the concentration, in M, of each of these solutions.
a 29.0-g sample of water at 270. k is mixed with 48.0 g water at 340. k. calculate the final temperature of the mixture
Balance the following equation by the half-reaction method for the pH conditions specified: H2CO (aq) + Ag(NH3)2+ (aq) ? HCO3- (aq) + Ag (s) + NH3 (aq) (basic)
Which indicator would be the best to use when titrating ammonia with nitric acid? Kb of NH3 is 1.8 x 10-5.
Calculate the pH of a solution containing 25.00 mL of 0.12 M formic acid (Ka = 1.7 x 10^-4) to which the following amounts of 0.10 M NaOH have been added
Calculate the concentration of NO3- ion remaining in solution.
suppose that a 5.0X10^-5 M solution of Ba(OH)2 is prepared. What is the pH of the solution?
They provide an alternative path for protons to re-enter the mitochondrial matrix, so ATP synthesis decreases. Electron flow and proton pumping are not inhibited.
Calculate the [H3O+], pH, and the fraction of dissociation (α) in an aqueous 0.140 M NH3 solution. (Hint: You will need the Ka, located in the back of your textbook.)
One hundred fifty kmol of an aqueous phosphoric acid solution contains 5.00 mole % H3PO4. The solution is concentrated by adding pure phosphoric acid at a rate of 20.0 L/min
