What is the enthalpy of dissolution of NaCl in water?
The enthalpy of dissolution of NaCl in water is the amount of heat energy released or absorbed when NaCl dissolves in water.
NaCl is an electrolyte and sugar is a non-electrolyte what is the reason?
aq. solution of NaCl is dissociated into its respective ions That is sodium cation & chloride ion, the electrostatic force of attraction b/w the ions is overcome by hydration energy but in case of sugar which contains sucrose contains only covalent bonds,which do not break up by hydration energy.
Are lattice and cohesive energies same?
Lattice energy is energy required to separate ions to infinite distance with no more interaction. Cohesive energy is energy required to separate atoms to infinite distance with no more interaction.
What is the definition of enthalphy?
The lattice energy of an ionic solid is a measure of the strength of bonds in that ionic compound. It is usually defined as the enthalpy of formation of the ionic compound from gaseous ions and as such is invariably exothermic. The concept of lattice energy has initially been developed for rocksalt-structured and sphalerite-structured compounds like NaCl and ZnS, where the ions occupy high-symmetry crystal lattice sites. In case of NaCl, the lattice energy is the energy released by the reaction
What is 0.45 NACL?
.45 what? Grams? in that case its 0.45 grams of salt
What is salt and how does it form?
Salt is sodium chloride, NaCl. Salts are the products of an acid/base reaction; in this case: NaOH + HCl = NaCl + H2O
What is the mole fraction of 18 mol NaCl in a solution of 100 mol water?
The mole fraction of NaCl in the solution is calculated by dividing the moles of NaCl by the total moles of NaCl and water. In this case, the mole fraction of 18 mol NaCl in a solution of 100 mol water is 0.15 (18 mol NaCl / (18 mol NaCl + 100 mol water)).
Why do sugar dissolve faster then salt in water?
For dissolving any solute the solvation energy of the solvent has to be more than the lattige energy of the solute. In this case the lattice energy of Nacl[salt] is more than that of sugar. Hence it takes more time to dissolve in water. ---- Akashraj Ghosh.
Does NaCl has least binding energy?
If you think to lattice energy this is 789 kJ/mol for sodium chloride.
What is the solvent in NaCl?
Sodium chloride is a solute when is dissolved in water (the solvent).
Why NaCl is required for TBST?
Because the sodium chloride solution in this case is isotonic.
What is the molarity of 750 mL of NaCl solution that contains 21.04 g of NaCl?
To calculate the molarity of the NaCl solution, first convert the mass of NaCl to moles using its molar mass. The molar mass of NaCl is 58.44 g/mol. Then, divide the moles of NaCl by the volume of the solution in liters (750 mL = 0.75 L) to get the molarity. In this case, the molarity of the NaCl solution is 1.5 M.
