Sodium Hydroxide
(OP)
I'm trying to mix a solution of sodium hydroxide flakes in water, to achieve a concentration of about 5%. Can I verify this concentration by a hydrometer, pH or is there a titration I can use?
Any feedback would be appreciated. Thanks

A hydrometer should work since the specific gravity of sodium hydroxide solutions does vary with concentration, see here:

pH is not a good option since the value will be greater than 14 for your concentration, which is outside the standard capabilities of pH meters.

I find Caustic Pels (pellets) cleaner and easier to use.

I see the heating with Pels but the small, round shapes don't seem to cause nearly as much agitation in the water as flakes.
