Answer the following question in the essay box below. Effect of Solvent: Record the results. H2O = alcohol = glycerin = In which liquid is the salt most soluble? Using the concept of `'Like dissolves like," explain why you got the results you did. Explain how the choice of solvent affects the dissolving process. Effect of Pulverizing: Record of dissolving times. crystal = pulverized = Why are the dissolving rates different? Effect of Temperature: Record of dissolving times. cold = hot Using the concepts of kinetic energy, describe why you found the results you did. Effect of Stirring: Record the times necessary to dissolve each sample. Record of dissolving time. stirred = unstirred = Perform the experiment again using hot tap water this time. Are there any differences in the results between the cold water experiment and the hot water experiment? Explain. Conclusions: Review the four factors of dissolving you have just investigated. Given the correct solvent for a solute, what could you do to hasten the solution process? 1. 2. 3.

Many reactions take place in aqueous solution. when potential reactants are mixed, a reaction will occur if there is some driving force that favors the formation of products. it is often convenient to categorize reactions in terms of these driving forces: precipitate formation, in which an insoluble solid is formed, weak electrolyte formation, as in a neutralization reaction involving water, or transfer of electrons, as in a redox reaction. these reactions can be represented by full molecular equations, which contain all species in the reaction mixture, or by net ionic equations, which show only the species that actually undergo a change. the latter does not contain the spectator ions, which do not undergo a net change or do not take part in the reaction. part a when the following two solutions are mixed: k2co3(aq)+fe(no3)3(aq) the mixture contains the ions listed below. sort these species into spectator ions and ions that react. drag the appropriate items to their respective bins. view available hint(s) spectator ions ions that react part b what is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? assume that the contribution of protons from h2so4 is near 100 %.ba(oh)2(aq)+h2so4(aq)→ express your answer as a chemical equation. view available hint(s) nothing provide feedback
