Re: Solutions
Wow! Just what I needed! It's great to have something rather than the net to help make up the soultions needed!
Re: Solutions
Just looked at the chart and the first one I looked at was the copper sulfate. I think there is one little mistake with the decimal point in the conc sulfuric acid added in the 0.5M: should be 6.25ml acid not 62.5ml "0.5M 312g in 2.437.5 water add 62.5ml Conc. Sulfuric Acid for 2.5 Lt".
Sorry Labbie, hope it is an easy fix.

Re: Solutions
If the 0.1 M uses 12.5mL of sulfuric, then 0.5M needs 62.5mL.
It is correct, right??

Re: Solutions
You are correct Lada, It could be the way I put then in order. 1 Litre then 2.5 litres. Hey Ladies I am so pleased that you a checking it for me. I went over a few times, but I would love every one to check it. Then we can say its correct and use it with confindence.
Thank you so very much.

Re: Solutions
Your solutions chart is fantastic and will help lots of us immensly. Whilst working thru it have noticed a small omission in Sodium Hydroxide. The 0.1M enrty doesn't specify an amount of water ,(ie 1 litre ) also same for first 2M entry. Could confuse the newer users.
