O ACIDS AND BASES Identifying the major species in weak acid or weak base... 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. 99 You will find it useful to keep in mind that HCN is a weak acid. do O acids: O On 1 mol of NaOH is added to 1.0 L of a 0.6M HCN bases: D solution. other: 1300 0.3 mol of HNO, is added to O acids: 1.0 L of a solution that is bases: O 0.7M in both HCN and KCN. other: 1301 Explanation Check © 2022 McGraw Hill LLC.

Could someone help me with this? I don't understand how hydrolysis, salt, acid, or % dissociation fit into this. I thought we were just supposed to take the -log of H+ to measure pH. Do we have to think about how each breaks down into certain ions? If you don't mind, if someone could explain this for me with the terms I'm confused about?
b) Determine the formula of the acid and the formula of the base to which each salt is related and put it them the appropriate columns in Table IV. using A= Acidic Salt, B = Basic Salt, and N = Neutral Salt. a) Copy your classification for each salt in Table III into Table IV. You can abbreviate in the "strength" (i.e. weak or strong) for each acid and base.

Identify each statement regarding strong and weak acids as true or false. You may ignore the self-ionization of water at the concentrations listed. The equilibrium concentration of hydronium ion for a 0.100 M solution of HCl is 0.100 M. ["", ""] The equilibrium concentration of hydronium ion for a 0.100 M solution of HF is 0.100 M. ["", ""] Strong acids HX are in the form HX nearly 100% in aqueous solution. ["", ""] A solution of weak acid HA is likely to contain a much lower concentration of weak acid HA than of its conjugate base A–. ["", ""] A concentrated solution of a strong acid contains approximately equal concentrations of hydronium ion and conjugate base of the acid.
