We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. After that, the weight of solvent is added with the weight of solute to calculate the weight of solution. Dissolve such crystals and diluted to 100 ml (measuring flask). Then, if everything is ideal, use the equations: pH = 14-pOH pOH = -log [OH-] The concentration of hydroxide ( [OH-]) will be equal to the concentration of NaOH as NaOH is a strong base and will be completely dissociated in water.
