Please Help 3. Were there any metallic compounds that did not react with either the acid or the base? Write the type of metal, based on your examination of the periodic table.

1)KNO3 ( pottasium trioxonitrate (V)

2)Ca(NO3)2 (calcium trioxonitrate (V

Explanation:

1)KNO3 ( pottasium trioxonitrate (V)

2)Ca(NO3)2 (calcium trioxonitrate (V)

Thses two compounds are metallic compounds and does not react with either the acid or the base.

Write the type of metal, based on your examination of the periodic table?

1)KNO3 ( pottasium trioxonitrate (V) have a potassium element which belongs to group 2 of the Periodic table which is an alkaline metal and can react with water or steàm

2)Ca(NO3)2 (calcium trioxonitrate (V) has calcium metal element which is an alkaline earth metal in the Periodic table and they react with Hallogens

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
