    Just perfect

  • I used this with my after school science crew. The little, tiny, white scoops you sell were just the right size to measure out this chemical for the kids. It mixed well with the water using a stirring stick.
    Can ship USPS! Great for biodiesel!

  • I mix this one gram with one liter 99% isopropyl alcohol to make titration solutions for biodiesel. The fact that it is a powder and not a flammable solution allows it to be shipped USPS to communities that do not allow hazardous shipping. This is great for us up here in Alaska. Thanks!
