Asolution of hydrochloric acid is mixed with an equal volume solution of barium hydroxide. when ph paper is inserted into the resulting solution, the ph was determined to be 7.0. if the initial concentration of the hydrochloric acid solution was 0.5 m, what is the concentration of the barium hydroxide solution?

Which buffer would be better able to hold a steady ph on the addition of strong acid, buffer 1 or buffer 2? explain. buffer 1: a solution containing 0.10 m nh4cl and 1 m nh3. buffer 2: a solution containing 1 m nh4cl and 0.10 m nh3

Which fact represents evidence for the big bang theory?

Which best describes the present-day universe? opaque, expanding very slowly, stars produce heavy elements transparent, expanding at an accelerated rate, stars produce heavy elements opaque, expanding at an accelerated rate, stars produce only hydrogen and helium transparent, expanding very slowly, stars produce only hydrogen and helium
