A student was performing this experiment with an antacid tablet which contained C a CO3 but forgot to heat the antacid solution prior to starting the back-titration. As sodium hydroxide was added the student noticed the formation of an insoluble white precipitate. Would the presence of this precipitate cause the students experimentally determined volume of N a O H be incorrectly high or incorrectly low? Briefly explain. Hint: Carbon dioxide reacts with water to form carbonic acid.    Question 3 options:   Incorrectly high, the solution becomes more acidic if not boiled gently   Incorrectly high, the solution becomes less acidic if not boiled gently   Incorrectly low, the solution becomes more acidic if not boiled gently   Incorrectly low, the solution becomes less acidic if not boiled gently
