What is the formula of chapter solution chemistry class 12?
In chemistry, the concentration of the solution is how much of the dissoluble substance, known as solute, is mixed with another substance, called a solvent. The standard formula is C = m / V, where C is the concentration, m is the mass of the solute, and V is the total volume of the solution.What are the formulas for solutions and Colligative properties?
Colligative Properties Equations
The equations for the four colligative properties are as follows. Tf=?iKfm T f = ? i K f m where Tf is the change in freezing point of the solution, Kf is a constant, and m is the molality of the solution measured in kg/mol.What is solution Class 12 chemistry?
A solution is a homogenous mixture of 2 or more substances. The substance present In the larger amount (solvent) dissolves the substance present In the smaller amount (solute).- Solution is a homogeneous mixture of two or more substances in same or different physical phases. The substances forming the solution are called components of the solution. On the basis of number of components a solution of two components is called binary solution. Solute and Solvent.
