Q: The dimensions of \$K_{w}\$ are \$mol^{2}L^{-2}\$.

\$K_{w}\$ is a product of two concentration terms.

Q: If HCl is added to pure water at \$25^{0}\$ C the ionic product of water will be:

For ionic product of pure water:\$[H^{+}]=10^{-7}M\$\$[OH^{-}]=10^{-7}M\$Product, \$K_w=10^{-14}\$lonic Product Kw of water is dependent only on temperature so it will remain same, \$K_w=10^{-14}\$.Hence, the correct option is \$\text{C}\$

Question 1

The dimensions of $K_{w}$ are $mol^{2}L^{-2}$.

Accepted Answer

$K_{w}$ is a product of two concentration terms.

Question 2

What is a buffer solution?

Accepted Answer

Toppr Ask Answer

Question 3

The ionic product of water is $10^{-14}$. What is the $H^{+}$ ion concentration in 0.1 M NaOH solution?

Accepted Answer

NaOH is a strong electrolyte and completely dissociates in solution.Hence, $[OH^-]=0.1M$.The ionic product of water is $10^{-14}$.Hence, $k_w=[H^+][OH^-]=10^{-14}$ or $[H^+]=\dfrac {10^{-14}} {[OH^-]}= \dfrac {10^{-14}}{0.1}=10^{-13}M$.

Question 4

The addition of NaCl to AgCl decreases the solubility of AgCl because ________.

Accepted Answer

NaCl is highly soluble and when it is added to AgCl it decreases the solubility of AgCl because of common ion $Cl^-$ and solution become super saturated.

Question 5

Buffer Solution is prepared by mixing _________________.

Accepted Answer

A solution that resists change in pH value upon addition of a small amount of strong acid or base (less than 1 %) or when the solution is diluted is called buffer solution. An acidic buffer solution consists of a $\text{solution of a weak acid and its salt with a strong base. }$while basic buffer solution consists of a mixture of a weak base and its salt with strong acid.

Question 6

Acid dissociation constant is:

Accepted Answer

Option C is the correct answer.Acid dissociation constant is denoted by $K_a$. It gives a measure of the strength of an acid in a solution.

Question 7

If HCl is added to pure water at $25^{0}$ C the ionic product of water will be:

Accepted Answer

For ionic product of pure water:$[H^{+}]=10^{-7}M$$[OH^{-}]=10^{-7}M$Product, $K_w=10^{-14}$lonic Product Kw of water is dependent only on temperature so it will remain same, $K_w=10^{-14}$.Hence, the correct option is $\text{C}$

Question 8
