The pH of the solution is 2.54.
Explanation:
pH is the measure of acidity of the solution and Ka is the dissociation constant. Dissociation constant is the measure of concentration of hydrogen ion donated to the solution.
The solution of C₆H₂O₆ will get dissociated as C₆HO₆ and H+ ions. So the molar concentration of 0.1 M is present at the initial stage. Lets consider that the concentration of hydrogen ion released as x and the same amount of the base ion will also be released.
So the dissociation constant Kₐ can be written as the ratio of concentration of products to the concentration of reactants. As the concentration of reactants is given as 0.1 M and the concentration of products is considered as x for both hydrogen and base ion. Then the
[HB] is the concentration of base.
Then
So the pH of the solution is 2.54.
D Group A is soluble, and Group B is insoluble
6.00x10^9 Co atoms / 6.022x10^23 Co atoms = 9.96x10^-15 moles of Co
Hey mate here is your answer...
the correct option of the question would be CONCENTRATION ,because concentration of the reactant and product becomes equal at equilibrium.
hope it helps you..

The molecular compound in the given statement is CH₆N₂.
<h3>What defines a molecular compound?</h3>
Chemical compositions of molecules that make up molecular compounds reflect the number of elements that are really bound together within the molecule. Due to the sides and angles of a atoms' links to one another, the complex has a certain structure.
<h3>Briefing:</h3>
Consider 140.22 g/mol of compound
Carbon = 140.22 * 51.38/100
Carbon = 72 gm = 1 mol
Hydrogen = 140.22 * 8.64/100
Hydrogen = 12 gm = 6 mol
Nitrogen = 140.22 * 39.97/100
Nitrogen = 56 gm = 2 mol
The molecular compound is CH₆N₂.
