Why doesn鈥檛 water produce 10-7MH+, andwhen

is added?

Short Answer

Expert verified

HBr is a strong acid; when it is dissolved in water, it gets completely disassociated into H+and Br-

Step by step solution

01

Define strong acid

A strong acid undergoes complete dissociation in water. For example, HBr is a strong acid that undergoes complete water dissociation.

02

Explain the concentration of H+ ions

The concentration of H+ions released by water can be neglected when HBr is dissolved in it because HBr is a strong acid and undergoes complete dissociation. The concentration of H+ is merely due to HBr.
