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 HCN is a weak acid. 0.8 mol of KOH is added to 1.0 L of a 0.8M HCN solution. 0.15 mol of HI is added to 1.0 L of a solution that is 1.2M in both HCN and KCN. acids: bases: other: acids: bases: other: 0 0,0,...

Please refer to the example image to answer. You must use CER, claim-evidence-reasoning. Make sure that your answer is CLEAR. Claim is your answer to the question. Evidence is from the image and reasoning is your explanation. Proper evidence for all Lewis structures include: Carbon or most electronegative atom in center. Octet of electrons surrounding each atom. Total number of electrons depicted equals same total number of valence electrons from each participating atom. Make sure to refer to the example image. It shows what correct Lewis structures include.

The undissociated base (B) is present in the greatest concentration, with the products being present in relatively smaller amounts in this equilibrium mixture. How would this affect the magnitude of Kb? Do you expect it to be small or large? Which is the strongest base? Name of base Ammonia (NH3) Methylamine (CH3NH2) Ethylamine (C2H5NH2) Diethylamine (C2H5)2NH Pyridine (CSH5N) Kb value 1.76 x 10-5 Why? 4.4 x 10-4 5.6 x 10-4 Which is the weakest base? 1.3 x 10-3 1.7 x 10-9 Why? The larger the Kb the (stronger/weaker) the base. Since a weak base dissociates incompletely setting up an equilibrium, what method could you think of that you could use to determine the concentration of [OH"] ions given the initial concentration of the acid and its Kb?
