Or 2). Anything that melts other substances and does not dissolve when heated can be included in an acid.
How is gold recovered from a solution
Recovery from solution typically involves adsorption to activated carbon, then separating (eluting) the bulk gold from the carbon and passing the saturated solution through electrolysis, and then casting.
What happens to gold particles when they are mixed with water

The phenomenon of crystal water means that the substance contains a solid set of water molecules contained in a salt-like formula. Another name for this process is water hydration. Like water, molecules hydrate matter.
What does a polarimeter measure polarity of the substance angle of rotation of an optical active compound concentration of the substance PH of the substance
Description: A polarimeter is a scientific instrument designed to measure the angle of rotation caused by the passage of polarized light through an optically active substance. 2. A 0.1 g/ml solution of the bound pure R enantiomer in a 1.0 dm (ie 10 cm) polarimeter rotates the luminosity polarization plane by +4.8°.

Why did something different happen with substance A than with substance B when mixed with substance C
– Since substance C has properties different from properties A and B, it cannot become a mixture of A and B. – Therefore, C is a compound substance, since it is formed as a result of the joint reaction of A and B and the different properties of A and B. in equal degree.
