Insoluble. Metallic sulfides are very poorly soluble in water.
Things that are insoluble in water are called hydrophobes or hydrophobic.
It is hydrophobic, which makes it insoluble in water. But it soluble in organice solvents.
Yes, it is insoluble in water
If the salt is insoluble, any ions in water and the measured pH is the pH of water.
keratin
Fingernails (and hair and horns) are made of keratin, a tough insoluble protein.
Both keratin and collagen are biological structural elements, They are proteins that provide special properties combining strength and stability to the cells. These proteins are largely insoluble in water and generally elongated.
One example of a protein that is insoluble in water is collagen, which is a structural protein found in connective tissues such as skin, tendons, and bones. Collagen's insolubility in water is due to its triple helix structure and the presence of hydrophobic amino acid residues in its composition.
