1. Write the equation between HCl and H2O to form H3O+ and Cl-.
2. Write the chemical equation for the reaction of acetic acid and water to form acetate and H3O+. You can use Google images to find the structure of acetic acid if you did not write it down during prelab lecture. You want to draw in all the H, C and O bonds for acetic acid and acetate. You can write the equation directly on your paper. Circle the H atom that reacts with H2O. Using Google images, you should be able to find an image that answers this question.

(acacH+H2O =acac- + H3O+ ) hi, according to this equilibrium equation , is the following explanation correct? sodium acetate is the conjugate base of acetic acid(a weak acid). Its addition results in a shift in the acid dissociation equilibrium to the right. This also leads to a reduced proton concentration and consequently an increase in the pH of the solution . this increased acac- concentration caused the equilibria associated with the formation of the product complex to shift right to...

Acids are proton (H+) donors. Bases are proton (H+) acceptors. Acid-base reactions are often "reversible", meaning that they can occur in both a left-to-right and a right-to-left direction. As a result, there is one acid and one base on each side of an acid-base reaction. 1. Identify the Acids and Bases on both sides of the following reactions: a. NH4+ + OH- ⟷ NH3 + H2O b. HCl + H2O ⟷ Cl- + H3O+ c. H2PO4- + H2O ⟷ HPO42- ...
