Question

2. Does the calculated value of ascorbic acid per tablet agree with the value listed on the label? Give an explanation as to why it does or does not NG 4 Edit Answer 3. Suppose the beaker used to transfer the titrant was wet when you added the NaOH solution to it. How would this affect your reported amount of ascorbic acid? 4. How did you know if a salt solution was basic? Edit Answer 5. Can you use litmus paper to determine the pH of a solution? 6. Which property of an indicator do you need to know before choosing to use it in a titration?

Explanation / Answer

4.When a salt solution is basic, it turns the red litmus blue.

5.If a solution has pH less than seven that is acidic solution then blue litmus becomes red.

If the solution is basic that is pH is greater than 7,then red litmus becomes blue.

If the solution is neutral that is pH =7,then blue litmus remains blue and red litmus remains red only.

6. Indicator is the substance which exhibits different colours in different media.

It must change the colour abruptly based on the pH of the solution.
