For titration we will require
Acid-Base Tititration to measure the unknown concentration.
Used to find the molarity of a solution of an acid or a base.
one solution is taken in burette usually we take base
Another solution is taken in beaker it will be acid with a indicator
Indicator will change the color of the acid.
Now run base drop by drop into the beaker and keep stirring the beaker the solution will become colorless at one point that is called the end point note the volume run down in the burette. Repeat the same till you get two consecutive and the use the volume as V1 which will have some concentration let it be M1.
The volume of the solution taken the beaker is V2 and we have to find the unknown concentration of the soilution in the beaker That is M2.
Formula = M1 * V1 = M2 * V2
M2 = (M1 * V1)/V2
The method used here is acid based titration where we titrate a unkon concentration of base with acid to find the concentration of unkonwn acid.
The apparatus are : Burette(25/50mL) beaker(10mL) and a indicator (Phenolphthalein)
Apparatus: Goggles, Bench mat, 100cm3 beaker, 250cm3 beaker, 250cm3 conical flask, 25cm3 bulb pipette, Pipette filler, Burette, Burette stand ,and holder Plastic filter funnel, White tile, Teat pipette. Access to: your standard sodium carbonate solution dilute hydrochloric acid to standardise phenolphthalein indicator solution methyl orange indicator solution .
