Keeping properties of photo chemicals?

I just ran across some old photo chemistry and I'm wondering if it is still good to use. I have a partial bottle of Kodak indicator Stop Bath (75% full), and Orbit Bath wash aid that is in a 1 gallon collapsible bag in a cardbord box dispenser. They both are probably about 10 years old. Do these two chemical solutions go bad with time?

I know that overtime acids will lose their acidity. Mix it up. If its no good the bromocrestle purple will let you know.

Washing aids, like orbit bath, usually contain sodium sulfite which oxidizes rather quickly. If the chemical is in a powder form you don't need to work about this.

Yours;

Thanks Chris
