Write a net ionic equation to show how quinoline, c9h7n, behaves as a base in water.

Quinoline, acts a Bronsted-Lowry base as it can accept a proton, from water to form the conjugate base, . This reaction can be represented as,

Here in the reaction, the weak base quinoline accepts a proton from water to form the conjugate base of quinoline, and hydroxide ion,

Therefore the net ionic equation to show the basic nature of quinoline in water is,
