I get it!: Now I know that a neutralization reaction produces_________________________
Answer: An acid that reacts with a base to get salt and water.

I get it!: Now I know that, in water, acids produce ____________ _________ and bases produce ______________ _________.
Answer(s): hydrogen ions, hydroxide ions
What is the difference between a strong acid and a weak acid?
Answer: A strong acid dissociate to form hydrogen ions in a solution.
Interpret Data: Solution A has a pH of 1.6. Solution B has a pH of 4. Which solution has a greater concentration of hydrogen ions? Explain.
Answer: It would be Solution A because it is closer to 0 on the pH scale.
Make Generalizations: Is the pH of an acid-base neutralization always 7? Why or why not?
Answer: No it could be close to 7 because one might be a little more acidic or basic.
What is the difference between a strong base and a weak base?
Answer: Strong bases readily produce hydroxide ions in water. Weak bases don't produce hydroxide ions in water.
What is the pH of a neutral solution?
Answer: The pH of a neutral solution is around 7.
Define: How is the scientific meaning of salt different from the common meaning of salt?
Answer: The scientific meaning of salt refers to a specific group of compounds. The common meaning of salt is the stuff you sprinkle on foods.
What are the products formed when a base and reaction with an acid?
Answer: When acidic and basic solutions are mixed together, they produce a more neutral solution.
Which solution has a greater concentration hydrogen ions (H*), a solution with a pH of 3 or one with a pH of 7? Explain.
Answer: pH of 3 has the greater concentration of hydrogen ions because the lower end of the scale is more acidic.
