I’m assuming many people are gonna have to watch this in the future, this is greetings from the year 2021, hope however far in the future you are (even if it’s just minutes) is going well for you :)

I remember learning to do this in 3rd year chemistry. Now I’m in advanced higher where I actually had to use this because the lab technician in my school decided to give us a chemical we needed for an experiment as a dry powder instead of a solution.

At around 3:00 - 3:05, one can quite clearly see the double line in the neck of the flask, indicating that the viewer is not looking perfectly horizontally through the neck of the flask, and hence giving rise to parallax error. This should be avoided, and it should also be pointed out, as it gives rise to determinate error.

Write an experimental procedure (instructions) for preparing five calibration solutions. You should start with solid copper sulphate pentahydrate (molecular mass = 250 g mol-1) and prepare of a 100 mL aqueous stock solution of Cu2+ ions with a concentration of 0.1 mol dm-3. This stock should then be used to produce five calibration solutions with concentrations of 0.01, 0.02, 0.04, 0.06, 0.08 mol dm- 3. You should be specific about the glassware required and the masses and volumes used. Help me answer this question please

[@wadigkin95]

shouldnt the swirling/shaking of the volumetric flask be done after you rinsed it through the wall of the volumetric flask? And the turning the volumetric flask upside down should it be done?, wouldnt the solution touch the stopper and actually affect the final concentration...?

10% NaOH means how much should I weight take for the standard solution?

[@Berghiker]

What does that line mean? Why is it important?

[@shitakimushroom7058]

I'm here searching for the right solvent I would use to prepare a stock solution for my plant extract. I was looking for a solvent that would preserve the citral component of th plant extract that I will be using. But I can't still find it 😭

[@mozzan99ll93]

Thank you soooo much 🙏⬅️

[@ملاكالصامت-ح2ب]

How much water did you add at the beginning and how the weight of sample

[@Faisal-xb3zs]

Water at the start shouldn’t affect the standard solution as it is measured at the end in the long neck flask.

How to calculate the mass you need????😭

[@cremebrulee2484]

Assuming you have a desired concentration and volume. You find the moles of solute needed by multiplying the concentration (in mol/L) by the volume(in litres) then multiply the number of moles by the gram formula mass of the substance you are making a solution out of and that gives you the required mass.
