Question

how we can find hybridization for AsO3^3-

Answer 1

There are three steps to determining the hybridization of an atom:  

• Draw the Lewis structure 
• Use VSEPR theory to determine its shape. 
• Assign the hybridization.

Answer 2

firslty find total valence electrons= 5+ 6(3)-(-3)=26.then 26/8, divide remainder by 2, and then add quotient and remainder/2

i.e 3+1= 4 hence the hybridisation is sp3.
