The electrode reduction velocity constants of Calcium, Nickel and Manganese (Zinc) ions in various supporting electrolyte solutions and temperatures were measured by polarography. The rate constants of those ions calculated by Delahay's graphimetric method and Koutecky's method were matched in 50% of experimental error. This error would be accountable because of the application of thier approximate method. But there are magnificent differences between those values and Randles and Sentioomerton's. We, also, have attempted to deduce the simplified relation between velocity constant and electrocappilary characteristics, computing the velocity constant simply and rapidly, on which Kambara, lshii and Imai, Adachi had studied and established thier related equations using parameter x, y and z, for some limited range of x. And we have extended the equation to the wider range of y value than they did for the above mentioned ions.
