When 200ml of 0.11M hydrochloric acid (HCl) is mixed with 800ml of 0.10M methylamine (CH3NH2), write the net ionic reaction that favors products and occurs as the solutions are mixed. Then write the equilibrium reaction that you would use to solve the equlibrium system.
The EPA limit for lead in the water supply is 15 parts per billion by mass. Calculate the number of lead ions present in 1.00kg of water that is at the EPA limit for lead.
Based on your understanding of the relationship between acid/base behavior and chemical structure, match the Ka with each acid. Then calculate the pKa which corresponds to each value.
Find the concentration and pH solution - What is the pH of a solution of 0.65 M acid and 0.51 M of its conjugate base if the pKa = 5.30?
The Al2O3 does not react. If the sample residue weighs 2.675 g, what is the mass fraction of Fe2O3 in the original sample?
what is the molality of ethanol in a solution made by dissolving 14.6g of ethanol, C2H5OH, in 53.6 g of water?
