Which of the following is a base conjugate acid pair?
H2O and H30*
H20 and H2PO4
H2PO4 and HPO 2-

What is the ph of a 0.0010 m hno3? 1.0 3.0 4.0 5.0

When hydrochloric acid reacts with potassium hydroxide solution, the following reaction occurs. hcl (aq) + koh (aq) h2o (l) + kcl (aq) the reaction gives off heat energy, so it is an reaction.

Assuming complete dissociation of the solute, how many grams of kno3 must be added to 275 ml of water to produce a solution that freezes at -14.5 c? the freezing point for pure water is 0.0 c and k_f is equal to 1.86 c/m
