A chemical equation representing the reaction of water (HOH) and ammonia (NH3) is shown below.
HOH + NH3NH2 + OH
Which of the following statements best explains the chemical
action of the reactants in this equation?
o Both water and ammonia are acting as bases.
o Water is acting as an acid, and ammonia is acting
as a base.
o Water is acting as a base, and ammonia is acting as
an acid.
o Both water and ammonia are acting as acids.

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution
