Answer : The pH of a saturated solution is, 12.33
Explanation : Given,
=
First we have to calculate the solubility of ion.
The balanced equilibrium reaction will be:
Let the solubility will be, 's'.
The concentration of ion = s
The concentration of ion = 2s
The expression for solubility constant for this reaction will be,
Let the solubility will be, 's'
Now put the value of in this expression, we get the solubility.
The concentration of ion = s =
The concentration of ion = 2s =
First we have to calculate the pOH.
Now we have to calculate the pH.
Therefore, the pH of a saturated solution is, 12.33
1.54^-10 m, you bring the decimal point back to the position after the first whole number and count the places it took to get it there. If you're moving it backwards, the exponent will be negative, and if you're moving it forwards the exponent will be positive
Answer:
Ice floats on water because it is less dense than water. When water freezes into its solid form, its molecules are able to form more stable hydrogen bonds locking them into positions. Because the molecules are not moving, they're not able to form as many hydrogen bonds with other water molecules. Ice is a unique substance because it is solid-state — ice — is less dense than its liquid state. Because of this property, ice floats in water. Physical properties are characteristics of a substance. They do not change. Ice floats on water because it is less dense than water. When water freezes into its solid form, its molecules are able to form more stable hydrogen bonds locking them into positions.
The Coefficients would be:
Hg(CO3)2: 1
AgCl: 4
HgCl4: 1
Ag2CO3: 2
How do we know this?
Because if we look at the coefficent for the first compound, Hg(CO3)2, That means in total we have one Hg and 2 CO3's.
IF the coefficient is 4 for the next compound, AgCl, there are 4 Ag's and 4 Cl's.
Those were the REACTANTS to our equation. Now looking at the arrow, HgCl4 and Ag2CO3 are our PRODUCTS, or, what is FORMED from Hg(CO3)2 and AgCl. So, we need to make sure that they are equal, to obey the law of conservation of mass. So in simpler terms, if we have 4 Cl's on the reactant side, we need 4 on the products side.
So, if we had the coefficient of 1 for HgCl4, this makes sense, because on the products side we had 1 Hg, and 4 Cl's. With the coefficient of 1, we have 1 Hg and 4 Cl's on the products side, as well!
And if we had the coefficient of 2 for Ag2CO3, we would have 4 Ag's total and 2 CO3s, which matches on the reactants side, for we have two CO3's and 4 Ag's.
I hope I could help!
