Step 1
S be the solubility of Al(OH)3
Ksp=[Al3+][OH]3=(S)(3S)3=27S4
S4=Ksp27=27×101127×10=1×1012
S=1×103mil L1
Step 2
Solution of Al(OH)3: Molar mass of Al(OH)3 78 g. Therefore, solubility of Al(OH)3 in
gL1=1×103×78gL1=78×103gL1=7.8×102gL1
Step 3
pH of the solution: S=1×103mol L1
[OH]=3S=3×1×103=3×103
p[OH]=3log3
pH=14pOH=11+log3=11.4771

Step 1
Suppose the solubility is S mol L1. Then
Al(OH)3Al3++3OHS3S
Ksp=S×(3s)3=27S4
27S4=2.7×1011 or S4=1012 or S=103mol L1
Molar mass of Al(OH)3 in gL1=103×78=7.8×102gL1
[OH]=3S=3×103mol L1
pOH=log(3×103=30.4771=3.5229
pH=142.5229=11.4771

Step 1
The equation is as follows:
Al(OH)3(s)
AL3+(aq)+3OH(aq)
The solubility equation of Al(OH)3(s) is given above. The ionization of AL(OH)3(s) gives Al3+ions and OHions in water. The coefficient of Al3+ ion is one whereas the coefficient of OH ion is three.
Step 2
The solubility product expression Ksp is as follows:
Ksp=[Al3+][OH]3
Solubility-product expression for Al(OH)3(s) is Ksp=[Al3+][OH]3
NSK
Ksp of Al(OH)3(s) is the product of molar solubility of ions Al3+ and OH formed in the ionization of Al(OH)3(s). Therefore, the Ksp expression for Al(OH)3(s) is Ksp=[Al3+][OH]3
NSK
Solubility-product expression for Al(OH)3(s) is Ksp=[Al3+][OH]3

A 230kg crate hangs from the end of a rope of length L=12.0m. You push horizontally on the crate with a varying force F to move it distance d= 4.00m to the side.
a) What is the magnitude of F when the crate is in this final position? What are b) the total work done on it, c) the work done by the gravitational force on the crate, and d) the work done by the pull on the crate fromthe rope? e) Knowing the the crate is motionless before and after its displacement, use the answers to (b), (c), and (d) to find the work your force F does on the crate. f) Why is the work of your force not equal to the product of the horizontal displacement and the answer to (a)?
