Sodium hydroxide, also known as lye and caustic soda,[1][2] with the molecular formula NaOH is a caustic metallic base which is a white solid available in pellets, flakes, granules, and as a 50% saturated solution. It is soluble in water, ethanol and methanol. This alkali is deliquescent and readily absorbs moisture and carbon dioxide in air. Sodium hydroxide is used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, soaps and detergents and as a drain cleaner. Worldwide production in 2004 was approximately 60 million tonnes, while demand was 51 million tonnes.[3] Although molten sodium hydroxide also possesses similar properties, the high temperature required limits applications. 3M HCl .... Higher percent error and possibly a bad experiment. 2) obtaining a significantly smaller amount of SiO2 than was present in the original sample.
