Do you think these would work well to test for any left over metals in solution?
After neutralizing, when all that's left "should" be clear salt water, would that mess up the PPM "TDS" reading?
Will it be accurate enough that you can dump it down the sink?
If these wouldn't be good enough, can someone recommend one for me?
It would be used before disposing solutions made of HCl/H2O2, Cl and SMB. The solutions will be neutralized with either sodium or calcium hydroxide. (Using the proper disposal methods on here. Copper, filter, iron, Ph 9 back to Ph 7, etc.)

Also, after getting to the point of "salt water", if I decided to evaporate it, would it still smell like HCl, or lime?
