The solubility of a substance refers to its ability to dissolve in another substance. In the case of lithium bicarbonate, it refers to how easily it dissolves in water.
Basic solution: A basic solution, also known as an alkaline solution, has a high concentration of hydroxide ions (OH⁻). It has a pH greater than 7 on the pH scale and can neutralize acids.
Hydroxide ion: A hydroxide ion (OH⁻) is a negatively charged molecule consisting of one oxygen atom and one hydrogen atom. In basic solutions, these ions are responsible for the alkaline properties.
