Met expectations Review by
Sufficient quantity for 5 lab teams, adequate warning labels, came in a timely manner
A little goes a long way. Review by
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
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.
Great product, easy to use Review by
I used this pelleted product for two Apologia chemistry experiments. Mix the lye with vinegar in a container of cabbage water to show conservation of mass even though the solution changes color and heat is produced. Second, mix accurate quantities of lye and vinegar to measure the change in enthalpy of a lye-acetic acid reaction. I recommend using a digital mass scale to measure this product instead of using teaspoons, since the pellets are harder to measure accurately by volume than they would be if they were a powder -- but the pellets are much cleaner to use!.
