Explanation:
Food code is like sort of a guide to ensure that the food is presented according decent standards, unadulterated and correctly presented to the customer.

Answer: Dissociation constant of the acid is .
Explanation: Assuming the acid to be monoprotic, the reaction follows:
pH of the solution = 6
and we know that
As HA ionizes into its ions in 1 : 1 ratio, hence
As the reaction proceeds, the concentration of acid decreases as it ionizes into its ions, hence the decreases concentration of acid at equilibrium will be:
Dissociation Constant of acid, is given as:
Putting values of in the above equation, we get
Rounding it of to one significant figure, we get
