Beta, use the formula pH = -log √(Ka * C), assuming the dissociation is small. But yaar, that quadratic method they insist on in books... in my WagonR EMI, approximations work only until a certain amount. Same with acids—if it's too concentrated or Ka isn't tiny, that shortcut fails and you must solve properly. My daughter's maths homework gives me the same dread.
