About This Product
Students use calcium hydroxide to explore alkaline behaviour, the solubility of calcium compounds and how carbonates form. Prepared solutions are labelled with their name, preparation method, date and hazards. The powder can irritate skin, eyes and airways, so gloves, eye protection and dust control are used throughout.
Frequently Asked Questions
Q1. How is limewater made from calcium hydroxide?
The reagent is mixed with clean water, then the undissolved material is allowed to settle or is filtered off, leaving clear limewater for carbon dioxide testing.
