Need of blank titration?
to reduce error
What is the role of blank in formol titration?
Performing a "blank" titration is used as a reference for your real titrations. You obtain consistent results if you use the same endpoint color from your reference.
Why do not you use iodide salts in argentometric titration?
No use of iodide salts in argentometrics because AgI is very insoluble, about 1000 times less soluble then AgCl, originating from chlorides to be determined.
What do you mean by argentometric titration?
Argentometric comes from the Latin word ''argentum''which means silver. Argentometric titrations are precipitation titrations based on the use of silver nitrate as the precipitating agent.For example in titrations of halide ions,divalent anions,mercaptans(Ag2S),Fatty acids etc. By Lukato Simon Makerere University Kampala,Uganda Tel.0782528726.

What is blank titration?
Types of titrations 1. Direct titration: analyte + titrant → product 2. Blank titration: titration of a solution not containing the analyte (check for errors) If the endpoint is unclear, we can use a . . . Back titration a. Excess of standard solution is added to analyte (and they react) - Step 1 b. A second standard titrates the excess (unreacted) standard - Step 2 Step 1: analyte + reagent 1 → product + excess reagent 1 Step 2: excess reagent 1 + reagent 2 → product
Can a blank titration reading be greater than sample titration?
yes.

Is potentiometric titration superior to conductometric titration?
This is totally depending to WHAT KIND of analysis you are referring to. They could be of equal or of totally different value for one or another compound. Potentiometry is based on acid/base reactions and pH change at equivalence point, while conductometry is based in change of the (conductivity) behaviour of ions, also applicable to redox, precipitometric (argentometric) AND acid/base reactions.
Equation used to determine the iodine value?
Iodine value= (B-S)N x 12.69 ------------------- wt of sample where, B=titration of blank S= titration of sample N= normality of thiosulphate
What is the importance of blank titration?
it is mainly used to find out the errors, hence serve as a useful tool in precise measurements and accurate results.
What are the type of conductometric titration?
types of conductometric titration: acid base titration complexometric titration replacement titration redox titration precipitation titration
What are complexometric titration method?
Direct titration, Indirect titration, back titration, replacement titration and so on
What is over-titration?
over titration is when too much titrant is added to the analyte in a titration procedure.
