Drew Moyer Mrs. Haire IB Chemistry Experiment 6 Mole Ratio in a Chemical Reaction Background: Mole ratios of reactants are often times figured out by the use of the other products in a chemical equation. However‚ in the instance that the products’ mole ratios are unknown‚ it can be determined through the experiment. This method is called continuous variations. In this lab‚ I determined the mole ratio between Sodium Hypochlorite and Sodium Thiosulfate by using continuous variations of ratios

Shawn Dubbs Lab 1 The Mole Concept of and the Chemical Formula of a Hydrate Abstract: The objective of this lab was to conduct an experiment to analyze the molar components in alum. This was conducted by heating the alum till the water had evaporated and then determining the number of moles for each component. Then using the these amounts to figure out the empirical formula for alum. Results: In order to determine how much of each separate component a total mass was taken before hand for
