How will you prepare 100 times dilute solution from 1mL of concentrated sulphuric acid solution? What
precaution would you suggest and why?
Answers
Answer:
Explanation:
In order to dilute an acid, first of all you have to decide the concentration of desired (C2) and of course you have to know the concentration of the original acid solution that you wanna dilute (C1). In addition you have to decide the volume of interest of the diluted solution you gonna get (V2).
Make sure that C1 and C2 are given in the same unit for example both of them in molarity (M).
After you get these values you have to use this formula: C1.V1=C2.V2 which means:
solution's concentration x its volume = the diluted solutions' concentration x its volume
Using this formula you can get the value of V1. Now you know how much voulme you need to take from the original solution. In order to know how much water you should add to V1 calculate it by: V2-V1 the result is the amount of water which you have to add to V1.
Read the relevant chemical safety cards online and according to them you can start diluting your acid by adding V1 to the (V2-V1) water carefully.
