numericals on concentration of solution

Nitric acid can be concentrated up to 68%. It cannot be concentrated beyond this percentage by simply boiling because the aqueous solution of this concentration of nitric acid forms a constant boiling mixture at 121 o C. However, the acid can be further ..

Mass Percentage or Volume Percentage - The mass percentage of a component in a given solution is the mass of the component per 100g of the solution. For e.g., if W A is the mass of the component A, W B is the mass of the component B in a solution. The..

It is a solution that contains comparatively a higher proportion of the solute, compared to what it can dissolve at that temperatur..

Molality is defined as the number of moles of solute dissolved per 1000 g (1 kg) of solvent. Molality is expressed as 'm'. Mole Fraction is the ratio of number of moles of one component to the total number of moles (solute and solvents) present in the solution...

01. An object of mass 5 kg is lifted up through a distance of 2 meter. What is the work done? Solution: W = F x s Also, force acting on the object is F = mg [Newton's second law of motion] Mass of the object (m) = 5 kg Distance moved = 2m Therefore, Work done = F x s 02. How ..

01. A body of mass 2kg is raised to a height of 25m. Calculate the potential energy possessed by the body. Solution: Mass of the body (m) = 2kg Height (h) = 25 m Potential energy of the body = mgh 02. A bag of rice weighs 75kg. To what height is it raised if the work done in lifting it is..

01. A man of mass 60 kg runs up a flight of 60 steps in 40 seconds. If each step is 20 cm high, calculate his power. Solution : Since the man runs up a flight of steps, the work done will be equal to the potential energy. Height = height of one step x number of ste..

Concentration of an acid solution depends upon the percentage of the acid that is dissolved in wat..

Hydrogen Ion Concentration - In 1909, Sorensen introduced a term for expressing the concentration of hydrogen ions, which give an idea about the acidic and basic characters of the aqueous solution. This term was called 'pH' which means the 'power of hydrogen ions'. The..

Increasing the concentration of one of the reactants or decreasing the concentration of one of the products shifts the equilibrium in favor of the products. On the other hand, decreasing the concentration of one of the reactants or increasing the concentration..
