Acids and bases are defined by electron structure according to Lewis or Bronsted-Lowry?

Lewis

200

What has a high pOH?

Acid, it would have a high H+, and a low pH

200

How do you find the specator ions in an equation?

Find the repeating ions in both the reactants and products.

200

When adding a base to an acid during a titration, when should you stop adding the base?

When adding a few drops of the base causes a large increase in PH
