Aluminum weighing dishes. 2 Reagents. Those reagents needed to perform the standard viscosity test include the following: 1. 83 percent NaCl solution made from reagent-grade NaCl. 2. 1N NaOH solution. 3. 1N sulfuric acid solution. 3 Procedure. 1. Add 715 g of deionized (DI) water to a 1,000-mL beaker. 2. Stir with electric motor mixer to create a vortex of about two-thirds the height of the water. 3. 44-g active polymer. To do this, use the active polymer content stated in the product’s technical data sheet or request the information from the supplier.
