The preparations 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 HCH3CO2 is a weak acid acids: 0.7 mol of KOH is added to 1,0 L of a 0.7 MHCH,CO, solution IL, bases : other: 0.26 mol of NaOH is added toacids: 1.0 L of a solution that is 1.2 Min both HCH CO and CO2 and bases: D NaCH,Cop other:
Solution
1) HCH3CO2 + KOH ----> KCH3CO2 + H2O
KCH3CO2 IS BASIC.
answer: bases, CH3CO2- acts as base.
2)Â Â HCH3CO2 <----> CH3CO2- + H+
NaCH3CO2 ----> CH3CO2- + Na+
after addition of base(OH-),dissociation of weakacid(HCH3CO2) increases.so that, it gives formation of CH3CO2-. which is basic.
answer: bases, CH3CO2-
