Around the expected equivalence point of the titration, you need to drop the solution very slowly and mix the solutions very well because, around the equivalence point, just one drop of solution from the buret can make a radical pH change in the mixed solution. If the color of the solution in the erlenmeyer flask changes, record the volume of the solution in the buret and add a few drops of the solution to make sure the the equivalence point you found is correct.

What is the name of the process when you combine an acid with a base?
Titration. You add it one drop at a time...
Can a strong base be a biurette solution in titration?
No, because a drop of strong base can change the pH a lot and mess up titration, it has to be a moderate-weak base!
How do you get an accurate titration?
In Titration, to make sure we get a reliable and accurate result at first we will do a rough titration and we would do this by balancing the weigh boat to 0.00, use exact 2.5g of potassium carbonate, make sure the stopper your using is not broken and test it before using it. Look carefully at position of meniscus and it should be read from eye level. Raising the burette and glass pipette for every activity will help to reduce contamination, by doing these procedures we will get accurate results. After 25.9 cm make it drop by drop, to reduce the human error, there should be more than one person to do the experiment so they can get the timing right. Before using the conical flask, water it with distilled water
When performing titrations why should you constantly stir the contents?
During a titration, reactant from the burette are added drop wise. It may not reach the bottom, which might result in an incorrect endpoint. The flask is always stirred to mix the reactants in the flask evenly.
In a titration the point at which one drop of base turns the acid plus indicator a pink color that lasts for 30 seconds is called the?
The end-point

Why you use tritation?
there are many uses of titration..to know the volume of one drop of a liquid..
The point at which a drop of base changes the color of an acid solution and the color persists?
titration
What will happen to the molarity of NaOH If a drop of NaOH falls out of the flask during the titration?
You have to realise that a drop from the burette for instance is insignificant, if you are dealing with at least 10ml solution which you usually deal with on a titration. If you don't want to regard it as insignificant, then if NaOH is in the burette, then the solution doesn't become more concentrated with NaOH because that drop escaped.

Why KmnO4 is used as self indicator?
As we all know that the potassium permanganate (KMnO4) is the dark purple color solution ...and in titration it become colorless ....so when the titration is completed ...and the other single drop of KMnO4 solution produce pinkish colour in a beaker ...which indicate that the reaction was completed just a single drop before .. we use indicator in a a reaction in order to indicate ...but we dont used indicator in titration with KMnO4 because it also indicate us by changing its color ...colorless to pink

Where is the fuel filter on a 99 Suburban and what is the process for replacement?
It is unfortunately in the gas tank. You will have to drop the tank to replace it. The average cost from a shop is $1000 -$1500. I have done it and it isn't fun.
Can you drop an online class?
Yes, go through the drop process the college requires.
Should you drop economics for pyschology?
