The cube is quickly added to 100 mL of water at 23oC. What is the final temperature of the mixture? The specific heat of brass is 0.385 J/goC. The density of brass is 8.45 g/cm3.
A buffer is composed of 0.400 mol H2PO4^- and 0.400 mol HPO4^2- diluted with water to a volume of 1.00 L. The pH of the buffer is 7.210. How many moles of HCl must be added to decrease the pH to 6.210?
Why does the precipitate disappear when H2O is added? It is pushing the reaction to the left; why? It is not more reactant being added. It is changing Ksp but I thought only a change in temp would change K?
