Write a net ionic equation to show that quinoline, C9H7N, behaves as a Bronsted-Lowry base in water.
C9H7N (aq) + H2O---> C9H7NH+ (aq) + OH- (aq)
YOUR THE GOAT Garrett, over 4,493 people have seen this and yet you were the only one to come through with the clutch. Not to mention we're probably all here for the same reason. GLOOKS!!!
Sure, let me quinoline down the equation for you:
C9H7N + H2O → C9H7NH+ + OH-
In this reaction, quinoline (C9H7N) acts as a base by accepting a proton (H+) from the water molecule, forming a quinoline cation (C9H7NH+) and a hydroxide ion (OH-). So, quinoline goes from a basic mood to a positive mood in water!
To determine the net ionic equation for quinoline behaving as a Bronsted-Lowry base in water, we first need to understand the reaction between quinoline and water. In this reaction, water acts as an acid, while quinoline acts as a base. The net ionic equation will represent the species directly involved in the reaction.
The chemical equation for this reaction can be written as:
C9H7N + H2O → C9H7NH+ + OH-
To write the net ionic equation, we remove the spectator ions from the above equation. Here, the spectator ions are the cation C9H7NH+ and the anion OH-. These ions are formed from the dissociation of the weak acid-water. The remaining species directly involved in the reaction are:
C9H7N + H2O → C9H7NH+ + OH-
Therefore, the net ionic equation for quinoline behaving as a Bronsted-Lowry base in water is:
C9H7N + H2O → C9H7NH+ + OH-
To determine the net ionic equation for the behavior of quinoline (C9H7N) as a Bronsted-Lowry base in water, we need to first understand the definitions of a Bronsted-Lowry base and an acid.
A Bronsted-Lowry base is a substance that accepts protons (H+ ions) from an acid, while an acid is a substance that donates protons. When a base accepts a proton from an acid, it forms a conjugate acid and a conjugate base.
In this case, quinoline (C9H7N) will act as the base, accepting a proton (H+) from water (H2O), which will act as the acid. The reaction can be represented as follows:
C9H7N + H2O ↔ C9H7NH+ + OH-
Now, let's write the balanced molecular equation:
C9H7N + H2O → C9H7NH+ + OH-
To obtain the net ionic equation, we need to eliminate the spectator ions, which are the ions that appear the same on both sides of the equation. In this case, the spectator ions are H+ and OH-. Therefore, we can rewrite the equation as:
C9H7N → C9H7NH+
So, the net ionic equation for quinoline behaving as a Bronsted-Lowry base in water is:
C9H7N → C9H7NH+
