End point of titration should be at pH?

A titration usually has an acid (pH 0-6) in the burette and an alkali (pH 8-14) in the conical flask below the burette. Your aim is to neutralise the two solutions by titrating them against each other.So the endpoint pH should be 7 (universal indicator/litmus paper will appear a greenish colour). The solution in the conical flask is neutral.Hope this Helps!


Why do you use external indicator in diazotization titration?

external indicator is required in diazotization as to observe the end point of the reaction. internal indicators cannot give the endpoint because they may form complexes which may cause hindrance. for example, in the assay of sulfa drugs, iodine-starch paste is used as external indicator, because if we add iodine paste in the conical flask it will react with the reactants and give the blue-black coloration in the beginning of the actions, which will not tell the end point of the reaction. instead, the iodine-starch paste is applied in a paper, and the compound from the burette is added in small quantities into the sulfa drug solution, and after every few milliliters a drop of solution from the conical flask is dropped on the iodine-starch paste, when there is sudden change in colour, the addition from the burette is stopped. and observations are made.


Can an indicator provide an exact pH?

An indicator can provide exact pH if you are using the neutralization titration. Paper strip pH indicator are not an exact measurement but a high, medium, and low indication of acids and bases.


What is used to identify acids and bases?

an acid is a material or substance that is sour and can change blue litmus paper red a base is a material or substance that is bitter (it sometimes ) and can change red litmus paper blue. Litmus paper can tell an acid from a base Lemon Juice is an acid coffee is a base.


How you measure calcium concentration with EGTA titration method?

i didnt know what you need exactly but take this formula where we used to measure real calcium in serum (40-albumin)*0,08 then add the calcium result from lab paper

How do you house train your 6 month old llassa apsodoes business on paper inside but when you tke him outside he doesnt do it that often then when you go back in he does it?

If your dog always goes on the paper when inside this means the dog thinks that is where you want it to go to the bathroom. This makes training a lot easier. All you have to do is slowly move the paper outside, then get rid of the paper and make sure to praise the dog when it goes outside.
