Some solids are good conductors, some are not.
E. Conductivity(uS/cm) * 0.67 = TDS ppm
Physically, they are shiny, brittle solids with intermediate to relatively good electrical conductivity and the electronic band structure of a semimetal or semiconductor
Any fluid contains some solid in it which is dissolved in the fluid. the flow of current in the fluid is due to that dissolved solids. here the relation between electrical conductivity and total dissolved solids (TDS). so Tds meter works on the principle of electrical conductivity by measuring the electrical conductivity and relating it to the dissolved solids the TDS of any fluid can be determined.
yes because covalent have low conductivty
Low Melting Point. Most metals have high melting point and are solids at room temperature.
Mass and volume
For example the aptitude to form cations in solution. And generally metals are solids, hard, with good thermal and electrical conductivity, etc.
The denser a material, the better its conductivity. Gas is worse than solids.
Substances that are in form of solids offer the best conductivity compared to liquids and gases. The conduction may be sound, electricity or magnetism.
Electrical conductivity, water solubility, crystalline structure
yes
