STATION 1: KEY CONCEPTS
1. How does a weak acid differ from a strong acid?
A strong acid ionizes completely in water while a weak acid ionizes slightly.
2. List 3 properties of acids and 3 properties of bases.
Acids: tastes sour, donate H+ ions, are electrolytes, react with bases.
Bases: Feel slippery, are electrolytes, accept H+ ions, react with acids.
3. What is a neutral solution?
Has a pH=7. The concentrations of hydronium ion[H3O+] and hydroxide ion [OH-] are equal.
4. How are acids defined? How are bases defined?
Acids are defined as substances that donate protons or hydrogen ions. Bases are defined as substances that accept
protons or hydrogen ions.
5. What are the reactants and products common to all neutralization reactions?
Reactants: acid and base
Product: water and salt
6. What are indicators?
Are substances that change color depending on the pH of the solution.
7. How is the pH of an acidic solution? Of a basic solution? A neutral solution?
Acidic: pH<7
Basic: pH >7 Neutral : pH=7
8. A solution whose pH is 4 is acidic/neutral/basic? Acidic
