Question

A dye known as bromothymol blue appears yellow
under some conditions and blue under others, as
shown in the following equation
Which chemical would contribute a common ion if
added to this system?
CaCl2
NaF
HB(aq) +H(aq) +B"(aq)
yellow
blue
H2SO4
K2S04
DONE

Answer 1

Answer:

The second answer is that it will remain yellow

Explanation:

Answer 2

$H_2SO_4$ will contribute to common ion, as it will increase the concentration of the hydrogen ion in the solution and mark a shift to the equilibrium.

What is equilibrium?

In a chemical reaction chemical equilibrium is defined as the state at which there is no further change in the concentration of reactants and products.

Adding a common ion prevents the weak acid or weak base from ionizing as much as it would without the added common ion.

The common ion effect suppresses the ionization of a weak acid by adding more of an ion that is a product of this equilibrium.

Hence, $H_2SO_4$ will contribute to common ion, as it will increase the concentration of the hydrogen ion in the solution and mark a shift to the equilibrium.
