This is an application question on Acids, Bases & Salts that was sent to sean@simplechemconcepts.com by a local “Student X” to be shared and discussed with “chemists” in the world. Student X has also contributed her ideas and answers with the question.? Do leave some comments for Student X and other students reading this Chemistry Blogsite. Btw, i need to empahsize that it is ok to make mistakes now as we discussed questions.?It is?definitely better to make mistakes now as compared to mistakes during your examinations.
Question:
Use your knowledge of the nature of acids, bases and salts to explain the following observations or practices.Among other ingredients, cake mixes contain a solid mixture of tartaric acid and sodium hydrogen carbonate. The mixture can only ?rise? if water is added.
Student X’s suggested answer:
“Tartaric acid reacts with sodium hydrogen carbonate to give metal salt + water + carbon dioxide. Carbon dioxide released is trapped in the mixture, thus causing the mixture to ?rise?.”
