Question

1. Explain the data. Is there any evidence that a reaction has occurred?

2. Does the conductivity increase or decrease?

3. What is the indicator of the number of ions in solution?

4. How does this evidence indicate that the reaction has occurred between ions?

5. The Ba(OH)2 dissociates as Ba+² +2 OH. H2SO4 dissociates as 2 H+ +SO4-2. Write a balanced equation for this reaction.

6. When the conductivity is at a minimum, what must be true about the amount of Ba(OH)2?

7. Why does it not conduct at a low point?

8. Why does it conduct more before and after this minimum point?

If anyone has even one answer to any of these, that'd be really helpful!! Thank you! ^^​

Answer 1

The appearance of ions in solution makes a solution to conduct electricity.

What is conductivity?

Conductivity refers to the flow of current through a solution.

1) There is an evidence that reaction has occurred because of the formation of a precipitate

2) The conductivity decreases as more H2SO4 was added.

3) The indicator of the number of ions in the solution is the current recorded.

4) This evidence indicates that a reaction has occurred because the formation of a precipitate decreases the current.

5)  Ba(OH)2(s) ---->  Ba^2+(aq) + 3OH^-(aq)

H2SO4(aq) ---> 2H^+(aq) + SO4^2-(aq)

6) When the conductivity is at the minimum, It means that the   Ba(OH)2 is largely undissociated.

7) It does not conduct at a low point because there are no ions in solution.

8) It conducts more before and after this minimum point because of more ions in solution.
