Question

Please include charges on the species listed in the answer. Please clearly mark the list of species. Thank you!

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 HF is a weak acid. acids: 2.1 mol of NaOH is added to 1.0 L of a 1.3 M HF solution. bases: other: acids: 0.3 mol of HCl is added to 1.0 L of a solution that is bases: D 0.8 M in both HF and KF. other:

Answer 1

1) NO.OF MOLES= MOLARITY*VOLUME IN LITTER

SO HCL have 2.1 moles and HF have 1.3 moles.

so first mixture is base.

2) HCL have .3 mole and HF have .8 moles these makes mixture acidic because both are acids but 0.8 moles of KF makes mixture  buffer solution so net mixture is buffer .
