CH4 and PH3 are both covalent since they are composed both of non-metals.
<span>
CH4 is non- polar because of </span> London forces and<span> has a geometry of tetrahedral PH3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (IMF) . Since PH3 is polar, it has a stronger IMF </span>
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.
7 I believe is the correct answer
It depends on the pH level of the water.
