Question

A 1.00 liter solution contains 0.41 M ammonia and 0.32 M ammonium nitrate If Q.16 moles of hydrobromic acid are added to this system indicate whether the following statements are true or false , (Assume that the volume does not change upon the addition of hydrobromic acid.) A. The number of moles of NH, will increase B. The number of moles of NH,' will remain the same 3C. The equilibrium concentration of HO. will rernain the same D. The p?i will decrease. ? ? E.The ratio of INH1/ [NH 1 will increase Ratry Entire Group | 11:54 SAMSUNG Il 5 6 0
