Standardizing the NaOH solution by dissolving a measured mass of solid NaOH ensures that the concentration of the solution is accurately known and consistent for use in experiments or analyses.
No, solid compounds do not have a pH. pH is a measure of the acidity or basicity of a solution, not a solid compound. The pH of a solution can be affected by the solid compound dissolving in the solution.
This is known as a solid-liquid solution where the solid solute dissolves in the liquid solvent to form a homogeneous mixture. An example is salt (solid) dissolving in water (liquid) to form a saltwater solution.
Yes, dissolving sodium chloride in water is considered a physical change. This is because only the state of matter changes (solid to aqueous solution), and no new substance is formed.
Melting is a physical process where a solid turns into a liquid when heat is applied, such as ice melting into water. Dissolving is a chemical or physical process where a solid substance disperses uniformly in a liquid to form a solution, like sugar dissolving in water.
Evaporation of the solvent, or thing doing the dissolving, is most often the best method. That or super-heating the solution until it becomes over saturated, and the solid begins to settle at the bottom.
No, solid compounds do not have a pH. pH is a measure of the acidity or basicity of a solution, not a solid compound. The pH of a solution can be affected by the solid compound dissolving in the solution.
Melting and dissolving are not the same. Melting is the process of a solid turning into a liquid due to heat, while dissolving is when a solid substance mixes with a liquid to form a solution.
It is possible for a gas to dissolve into a solid, in which case you could say that the mixture of solid and gas is a type of solution. An example is hydrogen dissolving in platinum.
When a solid such as table salt is placed in a liquid that dissolves it (a solvent) such as water, it dissolves and passes into solution. When it is all dissolved there is no solid left, only the liquid salt solution. It is still solid while it is dissolving as the dissolution action can only take place at the surface of the solid. Removal of salt ions (sodium and chlorine atoms) from the solid exposes more solid underneath until all the solid is dissolved.
When a solid, liquid , or gas is dissolved in another substance, the result is a solution.

The molar heat of solution of a solid can be measured by dissolving a known mass of the solid in a specific amount of solvent and measuring the temperature change that occurs. By using the formula q = mcΔT (where q is heat energy, m is mass, c is specific heat capacity, and ΔT is temperature change), the molar heat of solution can be calculated.
Yes, a solid and a liquid can form a mixture through a process called dissolution, where the solid is dissolved in the liquid. Examples include sugar dissolving in water to form a sugar solution and salt dissolving in water to form a saline solution.
Solute which is the solid being dissolved Solvent which is the liquid the solid is dissolving into Solution which is the solute and the solvent mixed together Soluble which means that something will dissolve Insoluble which means that something will not dissolve Solubility which is how much something will dissolve and Saturated which is when a solution has dissolved that maximum amount of solute
This is known as a solid-liquid solution where the solid solute dissolves in the liquid solvent to form a homogeneous mixture. An example is salt (solid) dissolving in water (liquid) to form a saltwater solution.
A saltwater solution forms when salt is dissolved in water. Solids do not dissolve in gasses, though they can sometimes change from a solid state to a gaseous state in a process known as sublimation. This is not analogous to dissolving.
HCl is a gas. It's therefore very difficult to accurately weigh out the proper amount to use to make a solution of any given concentration, and as the solution sits, some HCl may escape as gas. In contrast, it's very easy to weigh out a solid base to high precision, and use a solution made from it to standardize the only-approximately-known HCl concentration.
