If 7 and 4 are exponents, take the derivative. You should get x^6(x+1)^3(11x+7), setting the derivative equal to zero gives you 0, -1, and -7/11 as critical numbers. Test numbers in the intervals [-12,-1], [-1, -7/11], [-7/11,0] and [0,10]. If the first derivative comes out po...
Given that the Ka of benzoic acid is 6.50 x 10-5, how would one prepare 0.500 L of a benzoic acid/sodium benzoate buffer of a desired pH of 4.00? The starting concentration of the benzoic acid is 3.00 M and the molecular weight of sodium benzoate is 144.10 g/mol.
