What is neutralization reaction.
100
What are the products of a neutralization reaction?
What is water and salt.
100
How does the taste of a base differ from the taste of an acid?
What is an acid is sour and a base is bitter.
100
A student tests his container of milk of magnesia. The pH of it is 10. What will the milk of magnesia most likely taste like?
What is bitter
100
What is the range of the pH scale?
What is 0-14.
200
What is any compound that increases the number of hydronium ions when dissolved in water?
What is an acid.
200
If I have a strong acid, what type of substance do I need to neutralize it?
What is a strong base.
200
What type of ions do acids have the most of? Bases?
What is acids have hydronium ions and bases have hydroxide ions.
200
If battery acid were to spill on a road, why would the road need to be shut down until the acid was cleaned up?
What is so the tires and cars don't corrode.
200
What pH is considered neutral?
What is a pH of 7.
300
What is OH-?
What is hydroxide.
300
What pH will neutralize a pH of 6?
What is pH of 8.
300
Describe the color changes of litmus paper for an acid and for a base.
What is for an acid, the litmus paper turns red and for a base, it turns blue.
300
A student designs an experiment to test the acidity of the water of several ponds near an industrial area. Which tool would best help a student obtain accurate data?
What is litmus paper, cabbage juice, or pH probe.
300
Would a pH of 11 be considered a weak or strong base? Explain.
What is a strong base because it is closer to the end of the pH scale than to 7.
400
Give two examples of indicators.
What is litmus paper and cabbage juice.
400
If Gail has a solution with a pH of 5, can she neutralize it with a pH of 10? Explain.
What is no because a pH of 5 has a concentration of 100 and a pH of 10 has a pH of 1/1000, so the pH of 10 would make it to basic.
400
Ms. Pounds was drinking a solution that is sour with a pH of 6.5, would her solution be considered an acid, base, or neutral? Explain.
What is acid because the pH is below 7.
400
Why would it be useful for a gardener or a vegetable farmer to use litmus paper to test soil samples?
What is so the farmer can see how acidic or basic the soil is to see if his or her crops can grow there.
400
What is the hydronium concentration of a pH of 6?
What is 10
500
Describe the pH scale.
What is a scale of 0-14 that shows acids, bases, and neutral substances.
500
If George had a solution with a pH of 4, what pH is necessary to neutralize the substance? Explain mathematically.
What is a pH of 10 because a pH of 4 has a concentration of 1000 and a pH of 10 has a concentration of 1/1000. When multiplied together, they cancel each other out.
500
A solution conducts electric current. Can you use this property to determine if the solution is an acid or a base? Explain.
What is no, because both acids and bases can conduct electricity.
500
How do acids and bases apply to our upset stomach challenge? (Describe two ways)
What is answers will vary
500
