Answer:
pH range of indicator is 5.4 to 7.4
Explanation:
An acid-base indicator are chemical substances that change in color when pH changes.
An indicator changes in color when the pH of the solution is equal to pKa of the indicator (Where pKa is defined as - log Ka).
<em>The pH range in which indicator changes in color is pKa ± 1.</em>
<em />
pKa of buffer is:
- log 4x10⁻⁷ = <em>6.4</em>
That means pH range of indicator is since 6.4 - 1 = <em>5.4</em> to 6.4 + 1 =<em> 7.4</em>.
<em>(5.4 - 7.4)</em>

Answer: 1)
Equilibrium constant is defined as the ratio of the product of concentration of products to the product of concentration of reactants each term raised to their stochiometric coefficients.
where [] = concentration in Molarity=
Thus
As the value of K is greater than 1, the reaction is product favored.
2)
3)
4) Reactions which do not continue to completion are called equilibrium reactions as the rate of forward reaction is equal to the rate of backward direction.
