Weigh out about 10 g of NaOH pellets and transfer them to 1 L bottle (preferably plastic as NaOH etches glass). Add about 600 mL of deionized water and mix until the NaOH dissolves. Add another 350 mL of deionized water and mix again.
The instructions suggests the dissolving of about 10 g of NaOH in 0.95 L of water to prepare the solution to be standardized. Calculate the approximate concentration of this solution.
