That makes sense. But where the heck did you get them?
Add these DROPWISE. I use KOH and HNO for my pH adjustments, lol... just be very careful, as concentrated strong acids and bases are dangerous, and should be treated as such:

-Wear gloves and eye protection while handling
-Store in shatterproof bottles
-Store in secondary containment adequate to hold the entire contents of the original bottle without overflowing
-NEVER store acids and bases in the same secondary containment
-Do not store oxidizers and acids together either (ex. hydrogen peroxide) or organic solvents and acids
-Check the containers regularly for leaks or cracks. Concentrated bases are pretty harsh on plastics, and even in poyethelyne (the best choice for storage, Nalgene brand bottles are made of this), you will lose bottle integrity over time.
-ALWAYS have very VERY clear labels on your chemicals!!!!! -Don't re-use containers
-Keep them away from small fingers.
