HSC trials in only a month (1 Viewer)

why the hell do you have trials in a month when i'm still in the middle of half yearly exams ?
When an acid donates a proton, it forms its conjugate base. When a base accepts a proton, it forms its conjugate acid

Acid, Conjugate Base, Base, Conjugate Acid


HCl Cl- OH- H2O
HNO3 NO3- NH3 H2O
H2SO4 HSO4- CN- HCN
NH4+ NH3 CO32- HCO3-

In general:

A base's conjugate acid can be created by adding a hydrogen or removing a hydroxide.
An acid's conjugate base can be created by removing a hydrogen or adding a hydroxide.
