The corrosion rate of zinc in solutions has been measured under a variety of conditions. Amalgamation and the presence of zincate ions lower this rate of corrosion. The effect of increasing KOH concentration on the rate of corrosion is different for nonamalgamated zinc than for amalgamated zinc. The temperature effect is also different for the two types of zinc electrodes.
