I get it!: Now I know that a neutralization reaction produces_________________________

Answer: An acid that reacts with a base to get salt and water.

A. ionic compound that can form from the reaction form from the reaction of an acid with a base. B. reaction between an acid and a base. C. H* D. series of numbers that indicates the concentration of hydrogen ions in solution. E. OH- Answer: A.

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.
