Acids and Bases: Investigation 1 - Acids, Bases, and pH

In Investigation One, you will analyze common acids and bases by measuring their pH. During this Investigation, you will:

  1. Determine the pH of several different solutions that contain acids.
  2. Determine the pH of several different solutions that contain bases.

Acids and Bases: Investigation 2 - Serial Dilution

In Investigation Two, you will dilute a solution of hydrochloric acid (HCl) using a technique called serial dilution and then determined the pH of the different dilutions. During this Investigation, you will:

  1. Prepare six (6) centrifuge tubes to perform a technique called serial dilution to dilute an acid five (5) times.
  2. Determine the hydrogen ion concentration of each solution by measuring its pH.

Acids and Bases: Investigation 3 - Neutralization

In Investigation Three, you will neutralize solutions of an acid using two different bases. During this Investigation, you will:

  1. Neutralize a solution of hydrochloric acid using an antacid medication, which is considered a base. 
  2. Neutralize a solution of hydrochloric acid (HCl) using a 150 ml solution of sodium hydroxide (NaOH) in increments of 10 ml.
  3. Measure the pH of the HCl solution each time 10ml of NaOH solution is added.

Acids and Bases: Investigation 4 - Performance Assessment

This Performance Assessment is designed to allow students to solve a problem using the:

  • concepts with which they have become familiar during the previous three Investigations, and
  • procedures used during the previous three Investigations.
