Introduction
baking hot tonic is a common household product. It is a natural heterogeneous that is much safer than most cleaning products. It holds several uses that range from playacting as a cleanser to helping acid indigestion. The A whenceium Baking Soda Company has decided to begin producing this product; however, alternatively of hiring quality control scientists, the job to analyze the product is universe placed upon us.
The object of our experiment is to determine the percent of Baking Soda, NaHCO3 , in a baking pappa sample containing impurities cognise by the company but unknown by us. The uprightness of the sample go away be determined through twain different experiments. Each provide include dissolving integrity gram into 25-30 milliliters of water. Once the purity has been found our objective is to then determine the type of impurities in the mixture. These impurities can be lithium, potassium, or calcium salts.
Materials used include a baking soda mixture. Solutions for the experiment include hydrochloric acid, calcium chloride, potassium chloride, and lithium chloride. Equipment that will be used include the MeasureNet, ring and ring stand, Kimiwipes, melting pot and lid, volumetric flasks, pipets, and the Bunsen Burner.
The spectrophotometer, titration, and warming to decompose are the third main method actings that will be used. First, we will use the method learned in experiment four on heating a compound in a crucible that will break down and give off water and coke dioxide gases. By finding the mass of the gases given off, we can then calculate the original mass of the compound we began with. We can in addition calculate the mass of NaHCO3 in our sample by apply the mass of gas given off through heating to a constant mass. Our second way of determining the percent mass of Baking Soda in the sample and verifying our initial results will be through titration. Because Baking Soda is a slightly basic compound, we can simply...If you want to find out a full essay, order it on our website: Orderessay
