Ionic Reactions Results B - Do your results agree with your expectations from the solubility rules/table? Our results seemed to largely agree with the established solubility rules/table; however‚ a few reactions with the commonality of being mixed with Co(NO3)2 (cobalt nitrate) [reference Row A‚ Columns 2‚ 3‚ and 4] seemed to have such a pale pink tone that it was difficult to decide whether that could have been a precipitate or the lighting in the area where the experiment took place.

If the solution appears milky than it is known as a precipitate reaction‚ meaning it is soluble‚ and that the ions separated and became surrounded by water. Precipitates in this experiment are electrically uncharged. To identify which compounds are

180 Lab 5: Ionic Reactions Submitted by Abstract: The purpose of this experiment is to work with aqueous solutions of ionic substances. Aqueous solutions are those solutions in which water is the solvent. When ionic substances are dissolved in water‚ the ions separate and become surrounded by water molecules. The focus of this experiment is on precipitates. The goal of this experiment is to study the nature of ionic reactions‚ write balanced equations‚ and to write net ionic equations for

Remember to include color for precipitates. Examine the reactions against both dark and white backgrounds. If there is no reaction for that combination of solutions write NR (no reaction). Before beginning‚ set up a data table similar to the Data Table: Solubility Rules Table in the Lab Report Assistant section. CAUTION

general‚ solubility rules can be used to predict the outcome of double replacement reactions. I have come to this decision‚ because almost all of the data recorded from the lab‚ with the exception of number 13‚ agreed with the predictions made beforehand. 2. Out of the 15 combinations‚ the observations made for the combination of number 13 (the reaction of lead (II) nitrate and barium chloride)‚ did not agree with what was predicted‚ based on the solubility rules. The solubility rules that were

Title of Experiment 12: The Effect of Ionic Strength on the solubility of an Electrolyte Aim: The purpose of this experiment was to determine the thermodynamics variable of enthalpy‚ ∆H for the dissolution reaction of boric acid in water. The solubility of boric acid was measured over a range of various temperatures by finding out at what temperature crystallization began for solution of different molarities. A graphical relationship between the natural logarithm of molal concentration and the inverse
