Which of the solution has normality equal to molarity?
Answer: 3) HNO3 has molarity equal to Normality. Normality = Molarity × Basicity. For HNO3 Basicity is 1.
Under what conditions are molarity and molality of a solution nearly the same?
Molality and molarity of a solution are identical for very dilute solution. i.e having higher amount of water as solvent. Example : Very less amount of NaOH in high amount of around 500 g water will have same value of Molality and molarity due to presence of high amount of water .
Is normality and Molality same?
Molality ( ) is defined as the number of moles of solute per kilogram of solvent. Normality ( ) is defined as the number of equivalents per liter of solution.
Is molarity of solution always equal to normality?
Molarity: M = moles of solute contained in one liter of solution. Where molarity describes the moles of a complete substance per liter of solution, normality describes only the moles of reactive species per liter of solution. Normality is always a multiple of molarity.
What is the relation between normality and molarity of the solution?
For some chemical solutions, Normality and Molarity are equivalent or N=M. This typically occurs when N=1. Converting molarity to normality matters only when the number of equivalents change by ionization. Here, basicity refers to the number of H+ ions that can be given by an acid molecule.
Why normality and molarity of HCl is same?
Molarity is the moles of solute in one liter of the solution and normality is the number of gram equivalents to the volume of the solution. The given statement is true because HCl is a monobasic acid. So, for hydrochloric acid the normality and molarity is the same (equal).
Under what conditions will the molality of a solute not be equal to its molarity?
Molality of a solution cannot be equal to the molarity of a solution. Until and unless volume of solution is equal to weight of solvent, molarity is never equal to molality.
What type of solution is molarity and molality?
Molarity vs molality
| Molarity (M) | Molality (m) | |
|---|---|---|
| Measure of | Concentration | Concentration |
| Definition | The moles of a solute per liters of a solution | The moles of a solute per kilograms of a solvent |
| Units | M | m |
| Equation | M = moles solute / liters solution | m = moles solute / kg solvent |
