Question

For each of the following problems, supply the word(s) that is (are) consistent with the statement, or perform the required operation. Where applicable, assume that each reaction proceeds as written. (a) Hydronium ion, H_3 O^+, reacts with hydroxide ion, OH^-, to produce what substance?____ (b) A solution has an HCl concentration of 0.0025 M. It's H_3 O^+ concentration is ______ (c) Identify the Bronsted acid on the reactant side of the following reaction: H_2 O + PO^3- _4 HPO^2- _4 + OH^- _____ (d) Identify the stronger acid in each pair: H_2CO_3 or HCIO_4;______ HF or H_2 O;____ (e) Which solution produces more H^+ in water, a 0.1 M H_3PO_4 solution or a 0.1M HBr solution?

Explanation / Answer

a. water (H2O)

b. concentration of H3O+ is 0.0025 M

c. proton donor is called bronsted acid. So, H2O is bronsted acid.

d. HClO4 is stronger acid

HF is stronger acid

e. HBr is stronger acid than H3PO4. So, 0.1 M HBr solution produces more H+ ions.
