Why do we crush solids before putting them into a solvent?

The answer is to increase the surface area of the solute.
You see it dissolves faster because there is a lot more water touching it when it is has a higher surface area.This can be achieved by crushing

Answer: Option (c) is the correct answer.

Explanation:

When we crush a solute then there will be increase in number of solute particles. This means that there is increase in surface area of solute particles.

Hence, more is the surface area of solute particles more will be the collisions between solute and solvent particles. Therefore, more will be rate of reaction.

Thus, we can conclude that we crush solids before putting them into a solvent to increase the surface area of the solute.

Nesterboy [21]

Anesthetic in dentistry consists of a mixture of dinitrogen oxide (N₂O) and oxygen gas (O₂), which is administered through an inhaler over the nose. Total pressure of the mixture ( $P_{total}$ ) is sum of partial pressure of N₂O ( $p_{N_{2}O }$ ) and partial pressure of O₂, ( $p_{O_{2} }$ ).

$P_{total}=p_{N_{2}O } + p_{O_{2} }$

$P_{total}= 740 mmHg, p_{O_{2} }$ =370 mmHg

So, $p_{N_{2}O }$ = (740-370) mmHg= 370 mmHg=370 torr

Hence, partial pressure of N₂O is 370 torr.

As, 1mmHg= 1 torr.

What is the hydrogen ion concentration in molarity if the hydroxide ion concentration is 7.609 10-13 ?

mihalych1998 [28]

Answer: The hydrogen ion concentration in molarity is 0.013

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pOH is calculated by taking negative logarithm of hydroxide ion concentration and pH is calculated by taking negative logarithm of hydrogen ion concentration

Putting in the values:

$pOH=-\log[7.609\times 10^{-13}]$

$pOH=12.1$

Now , $pH+pOH=14$

$pH=14-12.1=1.9$

$pH=-\log [H^+]$

$[H^+]=0.013M$

The hydrogen ion concentration in molarity is 0.013
