My PB left me several gallons of liquid shock. Looks to me to be just 12.5% chorine so can I use this to chordate my pool. I typically use 10% but can adjust the quantity down some.

You certainly can, and depending on its age, it may be close to ten by now. A regular addition will tell you well enough. Perhaps use just a bit shy of what you normally put in. No biggie if it's a touch high when you test, and you'll figure it out from there. Good luck!
Just for clarification to others who read this. Liquid chlorine, liquid shock and bleach are all chemically identical except for the percentage of chlorine. Bleach is usually 6%-8.25%, liquid chlorine is usually 10% and liquid shock is usually 12.5%. It varies by state.

To add more confusion to that bleach bought from janitorial supply companies may be anything from 1% - 12.5%, many places sell the 1% junk cheap, and it tends to keep janitorial staff from going through bleach so fast, or at least so many $$$$ of it.
Good point! If there isn't a percentage listed in the bleach bottle then don't buy it. It is watered down cheap stuff.
Most chlorines/bleaches have a date stamp some where on the bottle, with the year and what ever day of the year it was produced. That can give you an idea of how old it is.
Good point. Here's an older thread that explains it: Chlorine Date Code Decoder/Easy Way to Measure Strength.
