Try dissolving in water and this one doesn't dissolve in water. What's the cause?
Try applying it on the skin (when it dissolves in water) and it doesn't turn pink right away. What happened?
there is a solution Or any suggestions for further use?

hello


depending on the pH of the dissolving liquid.


I don't know when it's finished dissolving. How much pH formula can be measured?
