What are the major disadvantages of using an indicator to measure the end point in an acid-base titration?
they only work within certain ph ranges
What is an indicator blank?
During an experiment for chemistry, if an indicator will not work due to the lack of a reactant, the reactant can be added. You must then compensate for the added amount by creating a solution of the indicator and the the same amount of the reactant. The volume required in the blank titration must then be subtracted from the other results to obtain quality results. This is an indicator blank and how it is used.
What companies use titration in there work?
Answer Any company who has waste water usually titrates it before allowing it to go to the sewer system. Chemical company's titrate their chemicals and Paint companies titreate certain paints to see how much lead there is in the paint. These are three uses of titration.
What unknown quantity can be calculated after performing a titration?
Titrations can be used to work out the initial amount of moles of a substance (for instance the number of moles of iron in a tablet).
How does a chemical indicator work?
a chemical indicator lets you determine the equivalence end point that's only when the reaction takes place

Why you use two indicator?
Because the end-pointsof these titrationshave different pH values. A strong acid / strong base titration has an endpoint of pH 7, and an indicator that changes near 7 is useful. Phenolphthalein changes around pH 8.5 which is close enough for government work (so to speak).A strong acid - weak base titration will have an endpoint below 7, and so an indicator that changes over a range that is less than 7 should be used. Methyl orange changes around pH 4.

How do you change a rear indicator in a xsara Picasso?
my rear left indicator and alarm light doesnt work, hoe do I change the bulb?.
Define standardization and state how you would go about doing it.?
Standardisation is doing a titration to work out the exact concentration of the solution you want to use to determine the concentration of an unknown solution. You must know the moles of your known solution in order to determine the number of moles for your unknown solution. You must also use your indicator to show you when it has reached it's end point.
