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 HCH CO is a weak acid. O acids: bases: O other: 0.19 mol of NaOH is added to o acids: 2.3 mol of NaOH is added to 1.0 L of a 1.3 MHCH,co2 solution 1.0 L of a solution that is 1.4 M in both HCH CO2 andbases: KCH,CO2 O other:0 Explanation

Explanation / Answer

1. Basic since no of moles of NaOH - 2.3mol

While no of moles of acetic acid - 1.3 mol, excess NaOH is present in the mixture. Hence basic solution.

2. Acidic since it is an example for acidic buffer.

Mole of acetic acid is more than NaOH.
