Question

Use the pull-down boxes to specify states such as (aq) or (s). If a box is not needed leave it blank. If no reaction occurs leave all boxes blank and click on ''submit". Write the balanced NET IONIC equation for the reaction that occurs when ammonium bromide and potassium hydroxide are combined. This reaction is classified as. A. Strong Acid + Strong Base B. Weak Acid + Strong Base C. Strong Acid + Weak Case D. Weak Acid + Weak Base The extent of this reaction is:. A. Below 50% B. 50% C. Above 50% D. 100%

Explanation / Answer

The balanced reaction is

NH4Br(aq) + KOH (aq) ------> KBr(aq) + NH3 (g) + H2O(l)

The net ionic equation is

NH4+(aq) + OH- (aq) -----------> NH3 (g) + H2O(l)

The reaction is between a weak acdi and strong base .

NH4+ is a weak acid due to hydrolysis and OH- is a strong base.

The extent of this reaction is complete (100%) as it is acid base reaction to give a gas and undissociated water.
