PPT-Total Hardness Test

1 Label the two beakers with their respective names 2 Put 10 mL of sample in their respective beakers 3 Dip one test strip in sample beaker for 3 seconds 4 Remove and immediately match to the closest . The hardness of water is due to the presence of calcium and magnesium minerals that are naturally present in the water. The usual signs of a hard water supply are scaling inside kettles, poor latherin Lanthanides and Actinides . By: Danielle, . Krysti. , Lauren, and Nate . Rare-Earth Metals .
