The other substance containing sodium would be expected to make the cushion is NaClO or the Sodium hypochlorite. It is for all intents and purposes and synthetically particular from chlorine. Sodium hypochlorite is much of the time utilized as a disinfectant or a blanching operator.

\boxed{{\text{NaClO}}} would be needed to make the buffer.

Further explanation:

Buffer solution:

These solutions offer resistance to any changes in their pH if strong acid or base is added to them. Buffer solutions are basically aqueous solution consisting of weak acid and its conjugate base.

The alkalinity or acidity of any solution is governed by its pH. pH range varies from 0 to 14. Solutions that have pH less than 7 are acidic in nature, those with pH 7 are neutral and those with pH more than 7 are basic or alkaline in nature.

Categorization of buffer solutions:

Acidic buffer:

These solutions have pH less than 7 and are formed by weak acid and its conjugate base. For example mixture of acetic acid and sodium acetate form acidic buffer.

Basic buffer:

These solutions have pH more than 7 and are formed by weak base and its conjugate acid. For example mixture of ammonium chloride and ammonium hydroxide form basic or alkaline buffer.

Consider {\text{Cl}}{{\text{O}}^ - } as a base and its sodium salt becomes NaClO. {\text{Cl}}{{\text{O}}^ - } is strong base so its conjugate acid becomes weak. Since buffer is composed of aqueous solution of weak acid and its conjugate base, NaClO can be used to make buffer.

In fractional distillation, liquid can be seen running from the bottom of the distillation column back into the distilling flask
shepuryov [24]

Answer:

substances with a higher boiling point are returning back to the flask which allows another substances with the specific context temperature (lower boiling point) to boil over and be purified.

Explanation:

The reason it happens because the lower boiling point substance vaporizes and crosses over while the other substance is waiting for its boiling point to reach

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. An industrial ch
mamaluj [8]

Answer:

Explanation:

From the given information:

The equation for the reaction can be represented as:

2SO_2 + O_2 \to 2SO_3

The I.C.E table can be represented as:

                     2SO₂              O₂                   2SO₃

Initial:             14                  2.6                     0

Change:        -2x                -x                      +2x

Equilibrium:   14 - 2x          2.6 - x                2x

However, Since the amount of sulfur trioxide gas to be 1.6 mol.

SO₃ = 2x,

then x = 1.6/2

x = 0.8 mol

For 2SO₂; we have 14 - 2x

= 14 - 2(0.8)

= 14 - 1.6

= 12.4 mol

For O₂; we have 2.6 - x

= 2.6 - 1.6

= 1.0 mol

Thus;

[SO₂] = moles / volume = ( 12.4/50) = 0.248 M ,

[O₂] = 1/50 = 0.02 M ,  

[SO₃] = 1.6/50 = 0.032 M

Kc = [SO₃]² / [SO₂]² [O₂]

= ( 0.032²) / ( 0.248² x 0.02)

= 0.8325

Recall that; the equilibrium constant for the reaction 2SO_2 + O_2 \to 2SO_3 = 0.8325;

If we want to find:

SO_2 + \dfrac{1}{2}O_2 \to SO_3

Then:

K_c = (0.8325)^{1/2}

\mathbf{K_c = 0.912}

Since no temperature is given to use in the question, it will be impossible to find the final temperature of the mixture.
