required practical 1

Question 1

what does this practical involve?

Answer 1

making a volumetric solution and then using it to carry out a simple acid-base titration

Question 2

what is the method for making the volumetric solution?

Answer 2

1. calculate what mass of solid you need based on the desired volume and concentration of the solution
2. use a mass balance to weigh the solid into a weighing boat
3. pour the solid into a beaker
4. rinse the weighing boat thoroughly into the beaker using distilled water
5. add more distilled water until the solid is fully dissolved
6. pour the contents of the beaker into a 250cm^3 volumetric flask
7. use distilled water to thoroughly rinse the beaker into the flask
8. fill the flask with water until the meniscus touches the 250cm^3 line
9. put the lid on and invert gently to mix
