When compounds of manganese free from chlorides are boiled with nitric acid and dioxide of lead,[87] the manganese is converted into permanganic acid, which is soluble and tints the solution violet.
Manganese is also thrown down on the spiral as dioxide (MnO{2}), the solution at the same time becomes violet from the formation of permanganic acid.
The only effect of the increase in quantity of acid was to give the brown of perchloride of manganese instead of the pink of permanganic acid to mark the finishing point.
On electrolyzing a manganiferous solution of copper nitrate, red permanganic acid appeared in a stratum floating above the platinum disk coated with brown peroxide.
It is obtained by treating a solution of permanganate of baryta with sulphuric acid, when sulphate of baryta falls, and the permanganic acid remains dissolved in the water.
All other permanganates, as well as permanganic acid itself, give solutions of the same color.
When carbon dioxide is passed through a solution of a manganate a part of the manganese is changed into manganese dioxide, while the remainder forms a salt of the unstable acid HMnO{4}, called permanganic acid.
Permanganates are the salts of permanganic acid, HMnO4.
It dissolves in water to form a deep red solution which contains permanganic acid, HMnO4.
In both cases the characteristic coloration from permanganic acid is developed by the action of the current at the positive pole; this, however, disappears in the direction of the negative electrode.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "permanganic" in a variety of sentences. We hope that you will now be able to make sentences using this word.
