<p></p> <p><b>New page</b></p><div>===Sodium hydroxide===<br /> * A strong base<br /> * Stock solutions are 5 N and 1 N<br /> * Molecular weight 40.00<br /> * Exothermic reaction on solution<br /> * Stock solutions should be stored in plastic bottles, rather than glass.<br /> ** Glass bottles are etched by strong bases over long periods of time.<br /> * Stock solutions absorb carbon dioxide from the air, and gradually become neutralized.<br /> **Check normality every year, or remake solutions.<br /> * Very caustic, wear gloves during use. Wash extensively if spilled. A soap-like feel indicates that your skin has come in contact with the solution.<br /> * Neutralize with acid prior to disposal down the drain.</div>
