What is back titration and how does it work?
A back titration is similar to a direct titration, but a bit more difficult. When an end point is not easily identified due to no colour change, an excess volume of a reactant of KNOWN CONCENTRATION is added to the reactant of unknown concentration. Then the resulting mixture is titrated again (or titrated back) to find the volume of the unreacted reactant, which will tell us the amount that DID react with the solution of unknown concentration. You need to take into account the amount of excess reactant originally added. The relevant calculations can then be taken out. Hence there are three reactants namely A,B,C. Such that it is to find the purity of C. This titration is possible only if A and B can react with each other and A and C can react with each other but the product of A and C do not react with B.
Why is a titration done three times?
A titrations is done three times in order to achieve a concordant result. In order for the results to be valid two of you results have to be within 0.5 units of each other.
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!
How long does each stage of a butterfly life cycle last?
how long does the Ulysses butterfly spend in each stage
Why do rockets have stages?
they have stages because when each stage burns up all its fuel, the stage is ejected thus making the rocket lighter so it can travel further and/or higher.
What are the stages of the annealing process?
There are three stages in the annealing process. The first stage is when a metal is heated up and it is called the recovery stage. The second stage is called recrystallization and the third stage is called gain growth. Each stage represents a higher temperature in the annealing process.

Is Huntington's Disease level 1?
Huntington's disease appears to have five different stages. The time spent at each stage varies, and the skipping of stages, from stage one to stage three, for example, is not uncommon. But perhaps you have another 'Level One' in mind.

According to Kohlberg Do all people progress through each stage of moral development until they reach the highest stage?
False. One cannot skip stages, they are hierarchical; however, some people will not advance to the highest stages.
What are the characteristics of each stage of sleep?
Sleep stages are defined in terms of brainwave patterns, which can be measured by an electroencephalograph (EEG).
What happens to each stage in the multistage rocket when it uses up fuel?
The payload (the important stuff) in a multistage rocket is carried in the last stage. The earlier stages are there only for the purpose of boosting the last stage on its way. When each earlier stage is out of fuel, it separates and falls back to Earth.
