distilled water

  1. I tend to use distilled for everything - just out of habit (used to work in Uni) but my partner used to use tap water as he had no easy access to distilled at the School he used to work at.
     
  2. :rolleyes:
     
  3. I am trying to get my Deioniser working ! see other thread on here !!

    At the moment buying it in
     
  4. As a general rule we tend to use DI water for all our solutions. At least it means when making up in bulk you don't have to work about what a batch can and can't be used for or what it was made up with that way.
     
  5. Thanks for your input everyone. I will make all solutions with Distilled water from now on

    Have a great weekend

    Had me worried.. I thought I was showed wrong hehe
     
  8. Where were you based
     
  9. It rather depends on your tap water...
    Mine is very hard and reacts with the acid so I only use distilled for acids despite it only being fro KS3/4

  10. Distilled water for everything except sodium thiosulphate where the slightly higher pH aids the solution stability.
     
  11. If you add 1g sodium carbonate per L of Thiosulphate stability will be maintained.:);)
     
  12. Hi George,
    Can I add 1g of sodium carbonate to any concentration of thio solution or is it different?
    I have to make 40,32,24,16 and 8g/dm3 thio solutions on Friday.

    Thank you.
     
  13. I only ever use distilled water for making up solutions (especially dilutions of conc acids).
    If we're having a mass reagent making session we plan ahead and fill several aspirators with distilled water first so we have enough :)
     
  14. Distilled water for everything, even 11-16.

    It's the right thing to do! (Especially in a very hard water area)
     
  15. Used to when we were 11-18. Don't use it for anything at all, ever, now.
     
  16. Always used distilled. Have a stock of large containers ready to go in each room and by the still and top up when I see them get below a certain level.
