Select 1 next to the species that makes the solution with the lowest pH. Select 2 next to the species that makes the solution with the next higher pH, and so on. Notice that some of the rankings have been filled in for you already. Also notice that water is on the list. For that particular case, just compare the pH of pure water to the pH of the other solutions.

The preparaons of two aqueous solutions are described in the table below. For each solution, write the chemical formulas of the major species present at equilibrium. You can leave out water itself. Write the chemical formulas of the species that will act as acids in the 'acids' row, the formulas of the species that will act as bases in the 'bases' row, and the formulas of the species that will act as neither acids nor bases in the 'other' row. You will find it useful to keep in mind that HCN is a weak acid. acids: 1 mol of NaOH is added to 1.0 L of a 0.7 M HCN bases: solution. other: 0.57 mol of HCl is added to acids: 1.0 L of a solution that is bases: I 1.5M in both HCN and NaCN. other: I Explanation Check 2021 McGraw.HiN Education.
