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.
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
Why the titration flask need to be shake during titration?
so that the solutions mix properly
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 is a titration and what equipment would you need?
A titration is a process of nutrilising an acid. You would need a burette, a beaker and and acidic and alkali substance. Higher chem FTW
Can a blank titration reading be greater than sample titration?
yes.

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 if your the blank to my blank?
Would need to know what your referring to by the meaning "blank". Blank stare.
What are the type of conductometric titration?
types of conductometric titration: acid base titration complexometric titration replacement titration redox titration precipitation titration
What is8times blank equal?
Need the value of blank.
Why do you need to remove the funnel before carrying out the titration?
chicken
What are complexometric titration method?
Direct titration, Indirect titration, back titration, replacement titration and so on
