Water is the solute, barium iodide is the solvent, and the process is exothermic.
O Barium iodide is the solute, water is the solvent, and the process is exothermic
Barium iodide is the solute, water is the solvent and the process is endothermic
O Water is the solute, barium iodide is the solvent, and the process is endothermic.

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
