Acid & Base Scavenger Hunt

Ryann Park, Brandon Steward, & Michael Orr

Acid-Base Nuetral Solution

A solution is said to be acid-base neutral if its hydrogen ion concentration is equal to its hydroxyl ion concentration.

Acidic Solution

A solution is said to be acidic, or acid, if its hydrogen ion concentration is greater than its hydroxyl ion concentration.

Basic Solution

A solution is said to be alkaline, or basic, if its hydrogen ion concentration is less than its hydroxyl ion concentration.

Acids 1-6 ~ Neutral 7 ~ Basic 8-14

Procedure

1. Using a pipet, drop a droplet of your chosen household item onto the pH strips.

2. Match the color on the pH strips to the chart provided.

3. Based on the color, record the household item’s name matching with the pH level onto your table.

4. Take a picture of the pH strip next to the correct color on the chart and a label of your substance for your presentation.

5. Repeat steps 1-4 until all 12 pH levels have a household item by their name.
