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.

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

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.

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.
