Ward's® AP Chemistry Investigation 3: Gravimetric Analysis
Overview
At SEO in Sydney, we offer the Ward's® AP Chemistry Investigation 3: Gravimetric Analysis kit to help students understand the concept of gravimetric analysis and its application in determining the hardness of water.
What is Gravimetric Analysis?
Gravimetric analysis is a quantitative analytical method that involves measuring the mass of a substance or its constituent elements. In the context of this investigation, students will perform gravimetric analysis to determine the concentration of calcium ions in water samples.
Understanding Water Hardness
Water hardness refers to the amount of dissolved calcium and magnesium ions present in water. Hard water can have several negative effects, such as the formation of scale in pipes and reduced effectiveness of soaps and detergents. Through gravimetric analysis, students will learn how to calculate the concentration of calcium ions in water, thereby determining its hardness.
Investigation Kit Contents
The Ward's® AP Chemistry Investigation 3: Gravimetric Analysis kit includes:
- Chemicals necessary for the analysis
- Lab equipment
- Detailed instructions
Investigation Procedure
Students will follow these steps to conduct the gravimetric analysis:
Step 1: Sample Collection
Collect water samples from various sources, such as tap water, bottled water, or natural water bodies.
Step 2: Precipitation of Calcium Ions
Add a precipitating agent to the water samples, which will react with calcium ions to form a solid precipitate.
Step 3: Filter and Dry the Precipitate
Filter the solid precipitate and carefully dry it to separate it from any remaining liquid.
Step 4: Weigh the Precipitate
Accurately weigh the dried precipitate to determine its mass.
Step 5: Calculating Water Hardness
Using the mass of the precipitate, students will calculate the concentration of calcium ions in the water samples, providing insight into their hardness.
