aluminum hydroxide has a Ksp value of 2.0x10-32.  This indicates that aluminum hydroxide is miscible in water. that almost no aluminum hydroxide will dissolve in water. the amount of aluminum hydroxide that will dissolve in water cannot be determined from this value. that a significant amount of aluminum hydroxide will dissolve in water.

The names and chemical formulae of some chemical compounds are written in the first twa columns of the table below. Each compound is soluble in water. Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. Then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. For example, you know water itself will be present, so you can begin each list with the chemical formula for water (H,O).

Help with the following question

Aluminum hydroxide has a Ksp value of 2.0x10-32.  This indicates that aluminum hydroxide is miscible in water. that almost no aluminum hydroxide will dissolve in water. the amount of aluminum hydroxide that will dissolve in water cannot be determined from this value. that a significant amount of aluminum hydroxide will dissolve in water.

Henry's law may be expressed in different ways and with different concentration units, resulting in different values for the Henry's law constants. If mole fraction is used as the concentration unit, one algebraic statement of the law is: Pgas = KHXgas where k is the Henry's law constant in units of pressure, usually atm. At 25°C, some water is added to a sample of gaseous xenon (Xe) at 3.60 atm pressure in a closed vessel and the vessel is shaken until as much xenon as possible dissolves. Then 2.70 kg of the solution is removed and boiled to expel the xenon, yielding a volume of 1.08 L of Xe (g) at 0 °C and 1.00 atm. Determine the Henry's law constant for xenon in water based on this experiment. atm
