Which of the following is the net ionic equation for the reaction that occurs when a few drops of HCl are added to a buffer containing a weak base (B) and its conjugate acid (BH+)? B(aq) + OH−(aq) → BOH−(aq) BH+(aq) + OH−(aq) → H2O(l) + B(aq) H+(aq) + OH−(aq) → H2O(l) H+(aq) + B(aq) → BH+(aq) B(aq) + H2O(l) begin mathsize 12px style rightwards harpoon over leftwards harpoon end style BH+(aq) + OH−(aq)

H+(aq) + B(aq) → BH+(aq)

Explanation:

When an acid is added onto a buffer, it is neutralized by the base.

So we pretty much have;

HCl + Weak base

Since HCl completely dissociates in water, it is represented as;

HCl(aq) --> H+(aq) + Cl-(aq)

The weak base reacts with the H+

So our Net ionic reaction is given as;

H+(aq) + B(aq) → BH+(aq)

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
