THE BIG IDEA: You will be given exactly 0.3 grams of citric acid. You need to calculate how many grams of baking soda (NaHCO 3) should be added to make a fizzy Kool-Aid® drink that is “just right”. 1. Convert 0.3 grams of citric acid (H 3 C 6 H 5 O 7) into moles. 2. Use the mole ratio of baking soda (NaHCO 3) to citric (H 3 C 6 H 5 O 7 ...
6 kwi 2016 · Concentration Calculations Worksheet. Divide grams of solute by volume of solution in liters. Divide mass of solute by total mass of solution, multiply by 100 for percent. Percent composition is typically used for high concentration solutions. g solute % composition = g solution x 100.
Citric acid is a weak, polyprotic acid that undergoes the following reaction with sodium hydroxide: H3C6H5O7 (aq) + 3 NaOH (aq) → 3 H2O (l) + Na3C6H5O7 (aq) You will perform a titration to determine the concentration of citric acid in a clear soft drink.
25 maj 2017 · This activity uses citric acid and baking soda to produce the fizz in a beverage. Citric acid, H 3 C 6 H 5 O 7, is a triprotic acid with pK a values ranging from 3 to 6.4. It is highly soluble and often used in beverages to enhance flavor and add a pleasant sour fruity taste.
CHEM1102 Worksheet 8: Acids and Bases. Model 1: pH. Water is able to act as both an acid and a base and it is possible for water to react with itself in an acid-base reaction called the autoprotolysis or autoionization of water: H2O(l) + H2O(l) H3O+(aq) + OH-(aq)
