Degree of Hydration of Sodium Carbonate Titration(Complete) Flashcards
1
Q
What indicator is used in this titration and why?
Degree of hydration of sodium carbonate titration
A
Methyl orange.
Strong acid weak base.
2
Q
What is the procedure for carrying out this titration?
Degree of hydration of sodium carbonate titration
A
Weigh out an accurate mass of crystals. Dissolve in deionised water( weak base) Make up to mark in 250cm3 volumetric flask. Invert 10 times to make the solution homogeneous. Pipette(20cm3) into conical flask. Titrate with a standard solution of HCL. Add methyl orange indicator. Endpoint- solution turns red.
3
Q
What is the colour change of this titration?
A
Yellow/orange to red.
4
Q
Identify a primary standard reagent which could’ve been used to standardise the hydrochloric acid solution.
A
Androhydrous sodium carbonate.
5
Q
Why were no more than 1-2 drops of indicator added?
A
Because indicator is a weak acid/weak base.
6
