Sufficient quantity for 5 lab teams, adequate warning labels, came in a timely manner
A little goes a long way.
Review by Joyce
We used just 3 little chemical "dots" per scientist to dissolve in water for making invisible ink. The kids could see the sodium hydroxide becoming a solution as it appeared to "smoke" from the bottom of the test tube. We had enough to do 2 different experiments with 20 young scientists, and I have plenty left!

We needed this for our unit in chemistry this year. We can't wait to use it. It was delivered very promptly.
Great product, good quantity for an always fresh supply
Review by Deborah H.
This product is a workhorse in our lab - we use a lot of NaOH, but we have small classes of homeschoolers, so we never use a lot at one time. I love the small quantities that I can purchase, so I never have a lot of excess chemical at one time. NaOH tends to absorb water, so buying small quantities when you need it is very cost effective. HST has very fast shipping, so I can easily purchase fresh NaOH, as needed.
