The accepted value for the heat of solution of NaOH is -44.2 kJ/mol
The value is 19,7 kJ/mol.

-4.52
It is not mandatory to heat this solution.
- 37.1 kj/mol is the heat of solution for lithium chloride.
exothermic solution is the solution which liberates energy in the form of heat.
use heat to heat the solution and add EDTA slowly to dissolve it.
Dissolution of sodium chloride in water is an exothermic process.
At 25 deg C, Heat= -176000 J approx
I suppose that these are synonyms.
Yes they soluble together. But they are nor reacting.
The easiest way is to shake the bottles, NaCl wil move easily and NH4Cl wont move very easily when shaken.
It is not mandatory to heat this solution.
The heat of solution for CaCl2 is -176,2 cal/g.
nh4oh + nacl however, it further decomposes to create NH3(g)+H2O(l)+NaCl(aq) so the full thing is NaOH (aq) + NH4Cl (s) ---> NaCl (aq) + H2O (l) + NH3 (g) And the ionic equation is OH- (aq) + NH4Cl (s) ---> Cl- (aq) + H2O (l) + NH3 (g)
- 37.1 kj/mol is the heat of solution for lithium chloride.
You have to Heat it!
Heat the solution
exothermic solution is the solution which liberates energy in the form of heat.
there is no chemical change when ammonium chloride is added to water. NH4Cl + H2O + heat -> products. it also cold when it is dissolved in water.
