Consider the phosphoric acid (H3PO4 )/dihydrogen phosphate ( H2PO−4 ) buffer equilibrium. H3PO4+H2O↽−−⇀H3O++H2PO−4

Using Le Chatelier's principle, predict how the concentration of each substance changes by the addition of H3O+ .

Does the concentration of H3PO4 increase or decrease when H3O+ is added?
Does the concentration of H2PO−4 increase or decrease when H3O+ is added?
Does the concentration of H3O+ change significantly when H3O+ is added?
Does the pH change significantly when H3O+ is added?

Astudent is given a sample of a blue copper sulfate hydrate. he weighs the sample in a dry covered porcelain crucible and got a mass of 23.875 g for the crucible, lid, and sample. the mass of the empty crucible and lid was found earlier to be 22.652 g. he then heats the crucible to expel the water of hydration, keeping the crucible at red heat for 10 minutes with the lid slightly ajar. on colling, he finds the mass of crucible, lid, and contents to be 23.403 g. the sample was changed in the process to very light clue anhydrous cuso4. if there are again 100.0 g of hydrate, how many grams of cuso4 are in it? how many moles of cuso4? (hint: molar mass of cuso4 = 159.6 g / mole. what per cent of the hydrate is cuso4? you may convert the mass of cuso4 to moles.)
