Hi,
Thankyou for your reply i think i understand what you say about weight and volume but im still a little confused?
I have a book that says the following and i suppose this is whats weird i will quote it and see if you can make any sense of it for me ?
Quote:using battery acid sold at garages (33% dilution of sulphuric acid) is used then dilute 1 volume of acid to 2 volumes of water this would give a 10% solution.
The 10% solution is used for hard anodising.
If battery acid is diluted 1 volume of acid to 1.5 volumes of water then this would give a 12% solution
The 12% solution is used for general anodising.
So this is where im getting confused the LCD has a solution of 4.88% can this work? obviously it must but im just really confused by it all.
Thankyou in advance for any help.
Regards
Richard...
