The
Ksp of copper(I) bromide, CuBr, is 6.3
10
–9 . Calculate the molar solubility of copper bromide.
Solution
The solubility product constant of copper(I) bromide is 6.3
10
–9 .
The reaction is:
First, write out the solubility product equilibrium constant expression:
Create an ICE table (as introduced in the chapter on fundamental equilibrium concepts), leaving the CuBr column empty as it is a solid and does not contribute to the
Ksp :
At equilibrium:
Therefore, the molar solubility of CuBr is 7.9

Note that solubility is not always given as a molar value. When the solubility of a compound is given in some unit other than moles per liter, we must convert the solubility into moles per liter (i.e., molarity) in order to use it in the solubility product constant expression.
[link] shows how to perform those unit conversions before determining the solubility product equilibrium.

Many of the pigments used by artists in oil-based paints (
[link] ) are sparingly soluble in water. For example, the solubility of the artist’s pigment chrome yellow, PbCrO
4 , is 4.6
10
–6 g/L. Determine the solubility product equilibrium constant for PbCrO
4 .
Solution
We are given the solubility of PbCrO
4 in grams per liter. If we convert this solubility into moles per liter, we can find the equilibrium concentrations of Pb
2+ and
then
Ksp :
Use the molar mass of PbCrO
4to convert the solubility of PbCrO
4 in grams per liter into moles per liter:
The chemical equation for the dissolution indicates that 1 mol of PbCrO
4 gives 1 mol of Pb
2+ (aq) and 1 mol of
Thus, both [Pb
2+ ] and
are equal to the molar solubility of PbCrO

The solubility of TlCl [thallium(I) chloride], an intermediate formed when thallium is being isolated from ores, is 3.46 grams per liter at 20 °C. What is its solubility product?
The lymphatic system plays several crucial roles in the human body, functioning as a key component of the immune system and contributing to the maintenance of fluid balance. Its main functions include:
1. Immune Response: The lymphatic system produces and transports lymphocytes, which are a type of
asegid
to transport fluids fats proteins and lymphocytes to the blood stream as lymph
Anatomy is the study of the structure of the body, while physiology is the study of the function of the body. Anatomy looks at the body's organs and systems, while physiology looks at how those organs and systems work together to keep the body functioning.
Enzymes are proteins that help speed up chemical reactions in our bodies. Enzymes are essential for digestion, liver function and much more. Too much or too little of a certain enzyme can cause health problems

the normal temperature is 37°c or 98.6 °Fahrenheit is important for maintaining the homeostasis in the body
the body regular this temperature through the process called thermoregulation which involves brain skin muscle and other organ working together to maintain stable internal temperature
