Assignment Help Physics
Reference no: EM131872122

1. Calculate the hydronium concentration when the hydroxide concentration is 1 x 10-5 M.

2. If the hydronium ion concentration is 1 x 10-3,M, what is the pH?

3. If a solution has a pH of 2, what is the hydroxide concentration?

4. What is the pH of a 0.0001 M hydrochloric acid solution?

5. What is the pH of a 0.0001 M sodium hydroxide solution?

6. Hydrogen sulfide, H2S, burns in the presence of oxygen, O2, to form sulfur dioxide, SO2, and water, H2O. Is the sulfur oxidized or reduced in this reaction?

7. In balancing oxidation-reduction reactions, not only must there be a mass balance (the same number of like atoms on each side of the equation), but also a charge balance (the same number of total charges on each side of the equation). With this in mind, balance the following:

Sn2+ + Ag → Sn + Ag+

8. Given the reaction

Fe3+ + I1- → Fe2+ + I2

a. Balance the equation

b. Which element is being oxidized?

c. Which element is the reducing agent?
