The best way to remove all traces of solvent or liquid from a solid precipitate is to dry the sample in the oven in an evaporating dish at the appropriate temperature.
Precipitate is a substance become independent from an answer or suspension by chemical or activity usually as an insoluble amorphous or crystalline solid.
A precipitate is an insoluble solid that emerges from a liquid solution. The emergence of the insoluble solid from solution is named precipitation. Often the precipitate emerges as a suspension.
Precipitate can even form when the temperature of a solution is lowered. Lower temperatures reduce the solubility of salts, which can end in their precipitation as solids.
Precipitate is a solid formed by a change in an exceedingly solution, often because of a chemical action or change in temperature that decreases solubility of a solid.

Answer:
Copying existing technologies is less expensive than developing them independently
Explanation:
Taiwan was a country that was poor when it formed. The country though quickly developed and in just few decades became a developed country itself, with strong economy and high standard of living. The main reason why Taiwan was able to achieve this in such a short period was that it focused on modernization of the country, using the already developed technology in the West. Since Taiwan was using already developed technology, it was not using its finances to develop its own technology, so the economy was just getting income, without investing in technological development.
