#1 is hydroionic acid (HI)
#2 is phosphoric acid (H3PO4)
A weak acid is an acid that partially dissociates into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water.
Pka = - log ka
10.36 = - log ka
Ka = .......
The coordination number is 6. The outer Cl- ion isn't included, so you count 4 x NH3 and 2 x Cl- are within Co's coordination sphere.
Sn=2
C and O=6
Im pretty confident yet I forgot a bit.
