Potassium carbonate is an ionic lattice--a soluble salt--which is naturally occurring as a mixture of salts. After a electrolysis process (in industrial level), crystalline salt can be obtained. It is widely used in soap and glass industries to mix with other substances.
It is a pure substance
it;s pure.
Potassium is a metallic element and a member of the Alkali Metal group, it has the symbol K which is derived from its old name of Kalium.
its a homogeneous mixture
This is an ionic compound and if it is not mixed in solution or found with other substances, it is pure.
Soduim is a pure substance. But it is a mixture because it was pshsically combined. Soduim is a pure substance. But it is a mixture because it was pshsically combined.

its a homogeneous mixture
A mixture of sodium chloride, either sodium iodideor potassium iodide (the iodizing ingredient), and an anticaking agent like calcium carbonate or magnesium carbonate to prevent the formation of lumps and keep the salt pourable.
eggshell is a kind of compound CaCO3 (calcium carbonate)
This is an ionic compound and if it is not mixed in solution or found with other substances, it is pure.
Potassium metal is a pure substance. In fact, it is an element as well. The reason potassium metal is an element is that it only contains one type of atom (all atoms of potassium have the same number of protons).
pure substance?
Pure substance.
No, it is a mixture; rarely a drug is a pure substance.
Just like granite, marble is a mixture. However, unlike granite, marble is typically more than 90% calcium carbonate, so it might count as a pure substance. Marble is a type of limestone, so is a mixture.
No a mixture is by definition not a pure substance.
