Sodium hydroxide is a common and useful strong base. Special care is required to prepare a solution of sodium hydroxide or NaOH in water because considerable heat is liberated by the exothermic reaction. The solution may splatter or boil. Here is how to make a sodium hydroxide solution safely, along with recipes for several common concentrations of NaOH solution.
Amount of NaOH to Make Sodium Hydroxide Solution
Prepare solutions of sodium hydroxide using this handy reference table which lists the amount of solute (solid NaOH) that is used to make 1 L of base solution. Follow these lab safety guidelines:
If you do get NaOH on your skin, immediately rinse it with a large volume of water. Another option is to neutralize any base on the skin with a weak acid, such as vinegar, and then rinse with water.Additional Reference
Recipes for Common NaOH Solutions
To prepare these recipes, start with 1 liter of water and slowly stir in the solid NaOH. A magnetic stir bar is helpful if you have one.
