Problem: Adding 0.100 mol of ferric nitrate, Fe(NO3)3, to 1 liter of water will cause the pH of the solution to do which of the following?A. decreaseB. remain unchangedC. increase

FREE Expert Solution

We’re being asked to determine what would happen to the pH if 0.100 mol of ferric nitrate, Fe(NO3)3, is added to 1 liter of water.


Ionic salts are made up of positively charged ion (cation) and a negatively charged ion (anion). To determine if the ionic salt would be acidic, basic, or neutral, we need to identify the acidity or basicity of the cation and anion.

For cations:

transition metal

▪ charge of +2 or higheracidic
▪ less than +2 → neutral solution

main group metal
