Lilly Connor Unit 2-
Leaning Aim A
Concentrate on keeping up your standards:
Titration:
Equipment List:
•1 x 50 cm3 Burette
• 1 x 25 cm3 bulb pipette and pipette filler
• 1 x plastic funnel
• 250 cm3 conical flask
• Thermometer
• 1 x clamp
• White tile or White Paper
• 1 x stand
• Volumetric Flask
• Balance
• Pipette
• Weighing Boat
• Glass Rod
• Hydrochloric Acid
• Sodium Carbonate solid
• Methyl Orange Indicator
Part 1: (Preparing the standard solution)- Method:
Before preparing the standard solution, it important to thoroughly wash and dry
the equipment being used with distilled water, to ensure wasn’t contaminated by
any chemicals from previous practicals.
Also, the balance had to be calibrated before preparing the solution. To calibrate
a balance, you use a range of weights (0.1g, 1.0g, 10g, and 100g) and place
them one at a time onto the balance that has been set to 0. If the reading shown
on the balance is not true to the measurement of the weight, the balance is then
altered with a collaboration key to the true weight.
Once the scale was been collaborated and the equipment was been washed,
between 1.25 and 1.45 grams the sodium carbonate solid could be weighed in a
weighing boat (the final weight was 1.35g). The solid was then transferred into a
250ml beaker with washings in order to get all of the solid out of the weighing
boat.
