Titration Help!!! Urgent!

[jk1993]

Hi there. I'm doing an Investigation into the chlorine concentration in fruit vs canned fruit and need help with the calculations. I know how to get the moles of the chlorine reacting (I am using the Mohr titration method) with silver nitrate, but the problem is with how I added 20ml of the juice to 150ml of distilled water. eg

 

 

 

1. Determine the average volume of silver nitrate used

from your concordant titres.

2. Calculate the moles of silver nitrate reacting.

3. Use the following reaction equation to determine the

moles of chloride ions reacting.

Ag+

(aq)

+ Cl–

(aq)

→ AgCl

(s)

4. Calculate the concentration of chloride ions in the

diluted seawater.

5. Calculate the concentration of chloride ions in the

original undiluted seawater.

 

−1

, gL

−1

and g/100 mL (%).

 

Can someone do a detailed working for an example please? Or Just an example of 4 and 5 would be awesome. Cheers!
