Acid-Base Neutralization and Redox Reactions

These flashcards cover key concepts related to acid-base neutralization and redox reactions based on the provided lecture notes.

What happens in an acid-base reaction?

A hydrogen ion (H+) transfers from the acid to the base.

What is produced when an acid dissolves in water?

Hydronium ion (H3O+) is produced when an acid dissolves in water.

What characterizes strong acids?

Strong acids completely dissociate in water.

What is an example of a weak acid?

Acetic acid (CH₃COOH) is an example of a weak acid.

How do strong bases form in water?

Strong bases form hydroxide ions (OH-) in water.

Give an example of a strong base.

Sodium hydroxide (NaOH) is a strong base.

What is the result of an acid and a base reaction?

When an acid and base react, they produce salt and water.

What step is first in predicting the products of a reaction?

Predict the products.

What defines a redox reaction?

In a redox reaction, electrons are transferred from one species to another.

What does oxidation refer to in redox reactions?

Oxidation refers to the loss of electrons.

What does reduction refer to in redox reactions?

Reduction refers to the gain of electrons.

How can oxidation numbers help identify redox reactions?

If oxidation numbers change, it indicates a redox reaction.

What is the first step in determining oxidation numbers?

The sum of oxidation numbers equals the charge of the compound.

What happens if a redox reaction occurs in a basic solution after balancing?

Add OH- to neutralize H+ ions and form water.

What does the half-reaction method involve?

The half-reaction method involves writing net ionic equations and balancing them separately.

Give an example of a balanced redox reaction.

An example is the reaction between chromium and hypochlorite ions in a basic solution.
