When Salt Meets Ice

CSEF · 2005 Chemistry

Avikar S. Saini · Warren (Earl) Junior High School, Bakersfield

Overview

Objectives/Goals My objective for this project is to learn why salt melts ice and how it melts it. Methods/Materials For my project I need: Excess, NaCl, KCl, AlCl3, Ice 18 Clear Bowls and Glasses 6 Spoons Mortar Gloves Results My results showed that the NaCl melted the ice the fastest followed by AlCl3, KCl, Chalk, Sugar, and finally standard. Conclusions/Discussion My hypothesis proved partially right. I was correct about the salts melting the ice at about the same rate but I was incorrect about the salt and sugar. I went back and did some research on my project and I learned that chalk has some salt in it and that sugar is a covalent bond like water. A covalent bond shares electrons instead of transffering them like ionic bonds.

Summary statement

My project is about how and why salt melts ice.

Help received
