In the following net ionic equation, identify each reactant as either a Bronsted-Lowry acid or a Bronsted-Lowry base. HCN(aq) H2

vfiekz [6]

Answer:

Explanation:

The definition of acids and bases by Arrhenius Theory was modified and extended by Bronsted-Lowry.

Bronsted-Lowry defined acid as a molecule or ion which donates a proton while a base is a molecule or ions that accepts the proton. This definition can be extended to include acid -base titrations in non-aqueous solutions.

In this theory, the reaction of an acid with a base constitutes a transfer of a proton from the acid to the base.

From the given information:

$\mathsf{HCN _{(aq)} + H_2O_{(l)} \to CN^{-}_{(aq)} + H_3O_{(aq)}}$

From above:

We will see that HCN releases an H⁺ ion, thus it is a Bronsted-Lowry acid

$H_2O$ accepts the H⁺ ion ,thus it is a Bronsted-Lowry base.

The formula of the reactant that acts as a proton donor is HCN

The formula of the reactant that acts as a proton acceptor is H2O

Making the simplistic assumption that the dissolved NaCl(s) does not affect the volume

kvv77 [185]

*** 2 ***
if we assume volume NaCl + volume H2O = volume H2O.. i.e.. NaCl does not effect volume 

therefore.. the units of.. 
.. M = moles NaCl / L solution ≈ moles NaCl / L H2O 
.. density = grams NaCl / L solution ≈ grams NaCl / L H2O 
again.. that is our assumption 

so we can readily see that 
.. M = (1 mol NaCl / ___g NaCl) x (__g NaCl / L H2O) + 0 
ie.. 
.. M = (1 mol NaCl / 58.5g NaCl) x density solution + 0 

so.. we would expect.. 
.. m = 0.01709 mol / g 
.. b = 0
