What is the ionic product of water at 25 C?

Then you convert it to pH. But in pure water, the hydrogen ion (hydroxonium ion) concentration must be equal to the hydroxide ion concentration….

T (°C) Kw (mol2 dm-6) pH
25 1.008 x 10-14 7.00
30 1.471 x 10-14 6.92
40 2.916 x 10-14 6.77
50 5.476 x 10-14 6.63

What is partial dissociation?

Strong acids and strong bases refer to species that completely dissociate to form ions in solution. By contrast, weak acids and bases ionize only partially, and the ionization reaction is reversible. Thus, weak acid and base solutions contain multiple charged and uncharged species in dynamic equilibrium.

What is the effect of increasing pressure on the dissociation of PCl5 according to the equation?

When pressure is increased, the equilibrium will shift in the reverse direction so that the effect of increased pressure is nullified. Hence, with increase in pressure, the dissociation of PCl5 is suppressed and the degree of dissociation of PCl5 decreases. Was this answer helpful?

What will be the amount of dissociation if the volume?

Let, ​the number of moles of PCl5present is 1mole. The number of moles of PCl5dissociated to form PCl3and Cl2be α. The amount of dissociation is if the volume is increased 16 times of the initial volume in the reactionPCl5⇌PCl3+Cl2 will be 4 times. So, the correct option is A.

What is the major source of energy for dissociation reaction?

Answer. The major source of energy of a dissociation reaction is bond or the bond energy. A dissociation reaction is a chemical reaction in which the compounds are broken into two or more elements. If there is a chemical reaction, bonds break in the reactants, while new bonds form in the substance.

What is the opposite of dissociation?

The opposite of dissociation (dis-association) is association, or integration. So parts or aspects of ourselves which normally work together are associated or linked with each other in a seamless fashion.

What is dissociation constant in chemistry?

In chemistry, biochemistry, and pharmacology, a dissociation constant ( ) is a specific type of equilibrium constant that measures the propensity of a larger object to separate (dissociate) reversibly into smaller components, as when a complex falls apart into its component molecules, or when a salt splits up into its …
