How to calculate the negative logarithm of chemistry CHOOH Ka=1.8*10-4 Using its negative logarithm PKA = - 1gka So the pKa of chooh is 3.75 How to get 3.75 here
Just find out the value of common logarithm of data and add a minus sign before the value
pKa=-1gKa =-lg1.8×10-4=-(lg1.8+lg10-4)=-(0.255-4)=-(-3.75)=3.75
