In this lab, you will be actually using this information to di how much product will be made you will then calculate the percent yield gained from the amount that you actually recover % yield actual yield * 100% theoretical yield The reaction you will be working with should be familiar to you from elementary school science fait volcanoes: You will be mixing baking soda (NaHCO) with vinegar (CHCOOH) to generate carbonic acid H.CO, which breaks up into water and carbon dioxide gas) and sodium acetate (NaCH.COO), which is a food preservation additive b: Communication 1) If we mix 25 grams of sodium bromide with a 25 grams of potassium chloride, what will our theoretical yield of sodium chloride be in grams? Start by writing the BALANCED chemical equation. (6 marks) 2) If our actual yield from this reaction was 18 grams of sodium chloride, what would our percent yield for this reaction be? (marks) 3) Is the answer in question 2 reasonable? If so, explain why you think this was a reasonable answer. If not explain what is wrong with it and discuss possible reasons you might get this answer in the laboratory. (3 marks) 4) What are some factors that might cause our percent yield to be greater than 100%? What are some factors that might cause it to be less than 100%? Make sure you discuss specific cases of how both might happen. (6 marks)
