A Convenient and Easily Handled Source of Sodium A commercially available granular sodium-lead alloy, "dri-Na,"' is a convenient and moderately safe source of metallic sodium. It is easy to handle and weigh and gives reproducible results. I t contains approximately 8.8% metallic sodium and is reasonebly stable in air. Only 11y0of the sodium had decomposed in 8. 13-month-old bottle which h d been opened and closed repeatedly. If dri-Ne, is accidentally dropped into water it sinks to the bottom, As a result ignition of the hydrogen gas formed by the decomposing sodium is minimized.
