RMM of CaH2=20+(1x2)=22
Number of moles or formula units
=mass/RMM
=8.294/22
=0.377
Answer:
Explanation:
- The reaction of ionization of 3 - aminophenol is given below ,
The lone pairs of nitrogen attacks on the proton , and form a protonated 3 - aminophenol .
- It will be more soluble at pH = 2.0 than at pH = 8.0 , since , in acidic medium , the compound forms protonated 3 - aminophenol .
The
- The protonated 3 - aminophenol is absorbed in intestine more , due to its ionisable nature .
