Answer:
8.3
Explanation:
pH is the measure of the H+ or H30 (they r the same thing) ions in a solution. it is equal to -log[H+]. [H+]= Molar concentration of H+ ions.
Answer:
A. 0.0233
Explanation:
according to the equation,
no. of moles of KBrO3 : no. of moles of Br2 = 1 : 3
no. of moles of KBrO3
= ⅓ × 0.0700mol
= 0.0233 (3 sig. fig.)

Answer: <u>Molarity of solution is 0.751 M. </u>
Reason:
Given: weight of solute (LiF) = 17.8 g, volume of solution = 915 ml = 0.915 l
We know that,
Molarity = </span>

<em>Molecular Weight of LiF = 25.9 g/mol. </em>
</span>∴<span>,
Molarity = </span>
<span> =
0.751 M</span>
Answer: 1 . Unsaturated Solution
2. Saturated Solution
Explanation:
1 ..tedsaturauntionsolu----------- Unsaturated Solution
2. ratedsatulutisoon--------------Saturated Solution
An Unsaturated solution is defined as a solution which contains an amount of solute that dissolves completely since the amount of solute is still less than the maximum amount that can readily dissolve in such solution and an additional amount of solute if added continues to dissove in the solution. Here the solution is still less than the equilibrium point.
example include. Addition of salt or sugar in water and it dissoves completely.
A saturated solution is defined as A solution which contains a maximum amount of solute that an additional solute will no longer be capable of being dissolved further since its equilibrium point has been reached.
Example- The addition of sugar to water till it no longer dissolves
Carbonated water is a saturated solution saturated with carbon as can be seen in the air bubbles it gives offf in form of carbon.
