Now, seven molar nitric acid solution. And second, we want to find the concentration of hydronium in our seven molar sodium hydroxide solution. So, in the first step, we're going to do Part A. So, first we must write the odor ionization reaction for water. So two moles of water react to produce 1 mol of conjugate acid and 1 mol of conjugate base. Now, let's write the equilibrium constants equation or expression for our odorionization reaction.
