Practical 3 Title: Effect of dissolved Carbon Dioxide on the pH of Water Aim: To investigate the effect of dissolved carbon dioxide on the pH of water. Hypothesis: The dissolved carbon dioxide will cause the water to turn acid‚ lowering the pH when carbon dioxide dissolves in water in which it forms carbonic acid (H2CO3). Materials: Straws‚ distilled water‚ safety glasses‚ pH probe‚ computer‚ universal indicator‚ gloves‚ lab coats‚ measuring cylinder‚ data logger‚ printer

Every winter road salt is used on sidewalks‚ roads‚ and highways to melt snow and ice. These are to prevent human activates from turning into accidents. When the snow melts the road salt gets dissolved into the melted ice and snow and becomes a formula. This formula sinks into the land (soil mostly) and kills vegetation. The purpose for this exit project experiment is to find out what are the affects of road salt on plants. The reason for doing this lab is to find out what a

potatoes have faster water movement depending on the concentration of sucrose it was placed in. We had two sized potatoes‚ 6g and 10g‚ and placed each in three different dilutions of sucrose at 0.5M‚ 0.1M‚ and 0.05M. We also placed a 6g and 10g potato piece in water to act as a control. Based on the weight percent change over 60 minutes‚ the 6g potato piece had faster water movement than the 10g. This confirms out hypothesis that smaller potato pieces will have a faster rate of water movement. Introduction
