Soda Water Titration
The titration experiments between the three different brands and under the five different conditions showed varied results. As shown in Graph 1, the condition which tested most effervescent was when the soda water was under cold temperatures and the least effervescent temperature was when the soda water was warm. When left standing without the lid, the soda water proved to be least effervescent. As seen in the above graph, under cold temperatures, ‘Schweppes’ demonstrated that it was the most effervescent, but under warm and room temperatures ‘Woolworths’ brand was most effervescent. When the soda water was stirred, ‘Regal’ was recorded with the highest concentration of hydrogen ions, and tied with ‘Woolworths’ when left standing with the lid removed. These results were observed because when refrigerated the gas molecules in the soda water slow down and the bond between hydrogen ions becomes strong, enabling carbon dioxide to be released (Frederick, n.d.). Whereas when the soda water was warm or room temperature, the gas molecules inside it where active and broke the bonds of the H2O chain, which in turn released more carbon dioxide, making the soda water less effervescent. Like when the soda water was left standing for 48 hours, the gas molecules would have been most active as they had no added pressure, leaving the

Before drinking ‘Schweppes’ soda water it is best for consumers to refrigerate it. If the consumer were to buy any of the brands of soda water tested, they should keep them refrigerated before drinking them. The next best way of storing any of the brands of soda water would be to keep the lid on at room temperature. Overall, the consumer should purchase the ‘Schweppes’ soda water if they have a refrigerator, and if they do not own a refrigerator, the ‘Woolworths’ brand should be purchased, in order to get the most effervescent
