1. Addition of chloride ion, Cl-(aq) to the cobalt complex, [Co(H2O)6]2+ causes the formation of a second cobalt complex, [CoCl4]2- and H2O(l). Write a balanced net ionic equation for this reaction. 2. Re-write the balanced equation from above this time including heat in the equation as either a reactant or product.

I just did a lab on determination of an equilibrium constant through the reaction EtAc (aq) + H2O (sln) <-> EtOH (aq) +HAc (aq). For all initial concentrations, K was less than one. Which I know says that equilibrium favors reactants. One of the post lab questions is "After the titration of the solutions at equilibrium, how will the solution return to equilibrium? Which chemicals will increase and which will decrease? (Be careful with acetic acid) " I am not...

Part I Color changes of Methyl Violet. We will study the following reaction: HMV (aq) + MV (aq) + H* (aq) yellow greenish-blue violet Step 1. Place about 4 mL of distilled water in a regular test tube. Add two drops of methyl violet indicator. Record the color of the solution. Violet Next, add drop by drop, add 6M HCI. This forces equilibrium to be shifted to the left or right-circle the right answer). Adding HCl changes color from to...

I just did a lab on determination of an equilibrium constant through the reaction EtAc (aq) + H2O (sln) <-> EtOH (aq) +HAc (aq). For all initial concentrations, K was less than one. Which I know says that equilibrium favors reactants. One of the post lab questions is "Is the hypothesis that the equilibrium constant, K, really a constant not dependent on the initial concentrations correct? Explain your answer. " I am not sure how to answer this
