How are molecular weights found from titration?
The results of a titration will tell you the number of moles present in the analyte. If you then also know the mass of this analyte, you can calculate the molecular weight as mass/moles.
What is acid base titration used for?
The acid base titration can be used to tell how acidic a substance is. It helps for analyzing substances and their acidic concentration. It helps to predict reactions with other substances.
Why is GC MS better than titration?
Using GC MS (Gas Chromatography Mass Spectrometry) you may detect multiple substances within a sample and in very trace amounts. Titration will tell you the concentration of a solution, and is more subject to error.
When approaching the endpoint for titration how can you tell that you are very close?
when the colour persists/ stays for a longer period of time before going colourless again
Why is it important to swirl the flask when you are performing a titration?
It is just to thoroughly mix the reagents, in order to not have any un-reacted starting reagents. If you do not mix them thoroughly you cannot effectively tell when the titration is complete. The same effect can be attained using a stir bar with stir plate.
Why did some believe they had exceeded their authory?
First tell us who "they" are and what the occasion was.

What is an indicator and what are the common indicators used for pH?
They are molecules which change color at a certain pH. You can tell at which pH your solution is by using indicators and matching up their colors. See the Web Links to the left for some examples of indicators (there are many) and at what pH each one changes color.Application of pH indicators:Definition of Titration: Titration is a common laboratory method of quantitative/chemical analysis that can be used to determine the concentration of a known reactant.Definition of a Buffer: A mixture that is resistant to change( or in this case to pH change). These are usually made up of a weak acid and its conjugate base.Now that you know what a titration is then lets see what they are used for:* Titrations * BuffersAn indicator in a titration is used to determine the pH of the solution when the reactant and the products are at the equivalence point(when moles of H+ from acid= moles of OH- from base).

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.

How can a user tell who has awarded them a Trust Point?
Currently there is no way to tell who has awarded you a Trust Point.
What does Brutus tell the audience about his mental and emotional state at this point?
We cannot know what Brutus tells the audience at that this point if you do not tell us what this point is.
