From the stearate of soda, it appears to be 104; and from that of lime, 102.
The stearate of lead, by Chevreul, gives 109 for the atomic weight of the acid.
We may thus conceive how a small quantity of stearate or oleate of potash may resist the decomposing action of the soda salts.
When added to water containing calcium salts the insoluble calcium palmitate and stearate are precipitated.
Ordinary starch, or talcum, or the stearate of zinc is suitable.
This separates the stearate, and leaves a nearly pure oleate of lead.
