Does the R-0004 solution go bad? As I was running low on this, I noticed that the color of my pH tests was tending toward orange rather than red. At a certain point, determining a pH level became pretty much impossible. By then I had gotten a new bottle of the solution, and it performed as expected.

If the R-0004 phenol red goes bad it will turn towards more of a purple or yellow color.
How old was the reagent and dos you store it properly?

At most it was half a year old, stored in a closet inside with temps ranging from 70 to 78.

Taylor has started putting expiration dates on their reagent bottles. If your bottle was purchased in the last six months then it should have expiration date on it. If it only has a lot number on it, then it is actually older than 1-yr. You can call Taylor with the lot number and they can tell you the manufacturing date. If you purchased the reagent from a source online and it only has a lot id, it is entirely possible that they can sell you expired reagents. Only way to know for sure is to call Taylor.

Good to know. Thanks. Since the bottle is now empty and discarded, I'm not worried about it, but I will check for a date on the current bottle.
