    Mixing a 5% solution?

    Hi,
    I need to make a 5% solution of Sodium Thiocyanate.
    I have Sodium Thiocyanate 98% powder.
    If anyone with chemistry experience can let me know the measurements would be much appreciated.
    I looked up how to make a solution and quickly got confused.

    Many thanks,
    Peter

    To make a 5% solution dissolve 5g of substance with Isopropyl alcohol to make 100 mL. You have 100mL of 5% solution.

    Thanks for the reply. So just to confirm...
    I'm making the solution as part of a C-41 Bleach recipe I'm mixing:
    (Pot. Ferricyanide 90g, Pot. Bromide 20g, diSodium Phosphate 6.8g, Sod. Thiocyanate 5% Solution + Water to 1 litre)

    So is it okay to include the Isopropyl alcohol to this mix?

    Thiocyanate will not dissolve in i-propyl alcohol. Use water instead.
