Smoke is not a solution, it is a colloidal suspension of very fine particles in air.
No, solutions can be made with liquid solvents as well as solid solvents such as water or ethanol. Solid solvents can dissolve solutes to create solutions just like liquid solvents can.

No mixtures are solvents
The pH scale is designed for water-based solutions, not organic solvents. Organic solvents do not have a pH value because they do not contain hydrogen ions like water-based solutions.
No, solutions can be made with liquid, solid, or gaseous solvents. The solvent is the dissolving medium in which solutes are dispersed to form a homogenous mixture. Different solvents are used based on the solubility of the solute being dissolved.
Soaps are made by the process of saponification of fats and oils. Paints and solvents are solutions of various chemicals.
No, solutions can be made with both liquid and solid solvents. In fact, solutions can be formed using gases as well. The key requirement for a solution is for the solute to be evenly distributed within the solvent.
The solubility of ZnO varies in different solvents. ZnO is generally insoluble in water but can dissolve in acidic or basic solutions. It is more soluble in organic solvents like ethanol or acetone.
Liquid solutions can be made without water by using organic solvents such as ethanol or acetone. These solvents can dissolve various solutes to form liquid solutions without the presence of water. Other examples include solutions made with liquid ammonia or liquid carbon dioxide.
They are important because then the solution is not stable
all solutions consists of solute and solvents and solvents are always in liquid form. some may come in an emulsion form though, but still it can be considered as liquid .
