The following table gives some interesting results respecting this action of potassium bromide:

Toward the end of the reaction, a crust of potassium bromide may tend to cover the melted potassium hydroxide.

We therefore conclude, that either the niter or the small excess of potassium bromide, or both together, produce the change.

As to potassium bromide.

We prepare, then, a solution of potassium bromide in water containing in every 12 ounces of solution 1 ounce of the salt.
