Alka Seltzer Expirement Research The Expirement that the chemist will be conducting includes the following materials: hot water‚ room tepmerature water‚ cold water‚ and regular Alka Seltzer tablets. Research on Alka Seltzer in previous expirements shows that it dissolves faster in hotter temperatures of water. It also shows in previous expirements that Alka Seltzer dissolves slower in colder temperatures of water rather than hotter temoeratures. Alka Seltzer is an antacid that contains aspirin

by mass of NaCO3 in Alka-Seltzer Tablets Alka-Seltzer is an effervescent antacid typically used for pain relief and neutralizing stomach acid to alleviate indigestion. Alka-Seltzer tablets contain Aspirin‚ Citric Acid (CH3COOH)‚ and Sodium Bicarbonate (NaCO3). When the tablet is placed in water it undergoes an acid-base reaction and Carbon Dioxide (CO2) is a byproduct that causes the notorious “Fizz”. The objective of the lab was to measure the % of NaCO3 in an Alka-Seltzer tablet in different

harmful microbes. Fungal infections can be particularly dangerous‚ but we have developed many different antifungal medications that can usually deal with these infections. But how do antifungal medications work‚ and how effective are they? In this science project‚ we will test how well different common antifungal medications can stop the growth of baker’s yeast‚ a harmless variety of fungus often used in baking. Problem/ Objective : Determine how different antifungal medications slow or stop the growth
