Colligative properties depend on the amount of solute dissolved in a solvent. These set of properties do not depend on the type of species present. These properties include freezing point depression, boiling point elevation, osmotic pressure and vapor pressure lowering.
100 times less H+
A solution at ph 10 contains<u> </u><u>100 times less H+</u> than the same amount of solution at ph 8.
<h3>The pH scale: How does it function?</h3>
- The pH scale determines how acidic or basic water is.
- The range is 0 to 14, with 7 representing neutrality.
- Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7.
- In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.
<h3>How does the pH change when two acids are combined?</h3>
- An acid's strength increases with the quantity of hydrogen ions it releases.
- The pH of the strong acids is between 1 and 2.
- We may observe that there is no response when two acids of the same strength are combined.
- It's because the end product will be neutral and the pH won't change.
<h3>How is pH value determined?</h3>
There are two ways to measure pH:
- colorimetrically with indicator fluids or sheets
- electrochemically with electrodes and a millivoltmeter for greater accuracy (pH meter).

#SPJ4
Answer:
Approximately 
.
Explanation:
Note that both figures in the question come with four significant figures. Therefore, the answer should also be rounded to four significant figures. Intermediate results should have more significant figures than that.
<h3>Formula mass of strontium hydroxide</h3>
Look up the relative atomic mass of 
, 
, and 
on a modern periodic table. Keep at least four significant figures in each of these atomic mass data.
Calculate the formula mass of 
:
.
<h3>Number of moles of strontium hydroxide in the solution</h3>
means that each mole of formula units have a mass of 
.
The question states that there are 
of in this solution.
How many moles of formula units would that be?
.
<h3>Molarity of this strontium hydroxide solution</h3>
There are 
of formula units in this 
solution. Convert the unit of volume to liter:
.
The molarity of a solution measures its molar concentration. For this solution:
.
(Rounded to four significant figures.)
