1. Solubility in WATER Check solubility of four solutes in water (H2O). For each solute record how many teaspoons dissolved in 1/2 cup of water. NaCl: Start out with 4 small glasses (cups) and add 1/2 cup of water to each. Put 1/2 level teaspoon (tsp) of salt (NaCl) into the first cup and stir. If it dissolves within 1 minute; add another 1/2 tsp of salt and stir. Count the number of 1/2 tsps you are adding. Repeat until...

Week 17- Concept Questions When you have a firm understanding of the thermochemical solution cycle (hint go read Ch 11.2 if you have not done so already) you can predict whether a solute will readily dissolve in a solvent. Draw a diagram to represent the enthalpy components of Sodium Chloride dissolving in water (an exothermic process) and draw a diagram to represent the enthalpy components of decane-C Hy, dissolving in water (an endothermic process). Based off of the Holn for...

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
