Determine each of the following for a 0.100 M HBr solution:

b. pH

Determine each of the following for a 0.100 M HBr solution:

d. milliliters of the HBr solution required to neutralize 36.0 mL of a 0.250 M LiOH solution

One of the most acidic lakes in the United States is Little Echo Pond in the Adirondacks in New York. Recently, this lake had a pH of 4.2, well below the recommended pH of 6.5.

a. What are the [H₃O⁺] and [OH^-] of Little Echo Pond?

One of the most acidic lakes in the United States is Little Echo Pond in the Adirondacks in New York. Recently, this lake had a pH of 4.2, well below the recommended pH of 6.5.

c. One way to raise the pH (and restore aquatic life) is to add limestone (CaCO₃). How many grams of CaCO₃ are needed to neutralize 1.0 kL of the acidic water from Little Echo Pond if the acid is sulfuric acid?

H₂SO₄(aq) + CaCO₃(s) → CO₂(g) + H₂O(l) + CaSO₄(aq)

The daily output of stomach acid (gastric juice) is 1000 mL to 2000 mL. Prior to a meal, stomach acid (HCl) typically has a pH of 1.42.

c. The antacid milk of magnesia contains 400. mg of Mg(OH)₂ per teaspoon. Write the neutralization equation, and calculate the number of milliliters of stomach acid neutralized by 1 tablespoon of milk of magnesia (1tablespoon = 3teaspoons).
