    Both are ionic compounds only with two different cations which have very similar properties [Talking about K+ and Na+]. Cr's oxidation number is 6+ in both cases. YOu can use either of them in a chemical reaction. Don't worry about the NA or K. It has no effect. [assume you are dealing with the same compound]
