What does the . mean in Fe2O3.H2O ???

Chemistry

wariber [46]3 years ago

Alright so 
The "Fe" is just the symbol for Iron. Due to me not knowing if it is sitting above or below the baseline, but I'll assume it's below. This means that "Fe2" means there are 2 iron atoms.

And then the O3 represents 3 oxygen atoms in the compound. 

And then the H2O is just the chemical formula for water, which consists of 2  hydrogen atoms and one oxygen atom.

At 25 °C, an aqueous solution has an equilibrium concentration of 0.00253 M for a generic cation, A2+(aq), and 0.00506 M for a g
aleksandrvk [35]

Answer:

The equilibrium constant Ksp of the generic salt AB2 =  6.4777 *10^-8 M

Explanation:

Step 1: The balanced equation

AB2 ⇒ A2+ + 2B-

Step 2: Given data

Concentration of A2+ = 0.00253 M

Concentration of B- = 0.00506 M

Step 3: Calculate the equilibrium constant

Equilibrium constant Ksp of [AB2] = [A2+][B-]²

Ksp = 0.00253 * 0.00506² = 6.4777 *10^-8 M

The equilibrium constant Ksp of the generic salt AB2 =  6.4777 *10^-8 M
