WebOn the contrary inorganic bases - like NaOH, KOH, LiOH, Ca (OH) 2 - increase pH dissociating. Disclaimer - accuracy of the values shown, especially for the strong acids, is questionable. Depending on the source pK a for HCl is given as -3, -4 or even -7. WebAnswer (1 of 3): It is well known fact that NaOH is strong electrolyte which means that it approximately dissociates 100% in solution. So the concentration of OH^- is also 5 M so pOH = -log(OH^-) = -log(5)= -0.69 (pH can be negative too ) and it is also a well known fact pH depends upon temperatu...
