For the titration of an aqueous nitrous acid solution, HNO,(aq), with an aqueous strontium hydroxide solution, Sr(OH)2{aq), what do you
expect the pH of the solution to be at the equivalence point?
O Basic (pH > 7.00)
O Unable to determine the pH of the solution at the equivalence point without additional information
O Acidic (pH < 7.00)
O Neutral (pH = 7.00)
A chemical system is set up by placing some solid ammonium chloride in an ammonia solution.
The equilibrium established can be represented as follows:
NH4*(aq) + H2O(e) 2 H30*(aq) + NH3(aq)
The pH of the solution is taken, then a small amount of NaOH(aq) is added and the pH is taken
again.
What can be said about the change in pH for the solution?
The pH significantly increases because a strong base has been added to the solution.
The pH significantly decreases because a strong base has been added to the solution.
There is very little change to the pH of the solution. If anything the pH of the solution
decreases slightly.
There is very little change to the pH of the solution. If anything the pH of the solution
increases slightly.
