Ice Ice Baby

CSEF · 2008 Chemistry Fourth Award

Hannah N. Schuyler · St. Anne School, Laguna Niguel, Orange County

Overview

Objectives/Goals The purpose of my experiment was to determine the melting rate of ice with different concentrations of salt and sugar solutions. Methods/Materials 20 100 ml plastic cups 4 800mL plastic containers 220g salt NaCl(Ralph's Iodized Salt) WhirlPool Gold Freezer 220g sugar (Pure Cane Sugar) US Balance Professional Mini Scale US Magnum (500gx0.1g) 2,050mL tap water 100g balance calibration weight 5 funnels Stopwatch 5 100 ml graduated cylinders Masking tape Results The meting rates were: Frozen Solutions Melting Rate of Ice (mL/min) Control 0.20 1% Salt 0.25 1% Sugar 0.20 10% Salt 0.47 10% Sugar 0.26 Conclusions/Discussion My conclusion is that salt lowers the freezing point of water more than sugar does which causes it to melt faster.

Summary statement

My project is about determining the melting rates of ice with different substances and concentrations.

Help received

My mom double checked my work and made sure my measurements were correct. Mrs. Wentz answered all of my questions. Also, Mrs. Wentz and Mrs. Oggiano let me borrow their laboratory equipment.
