A buffer solution is made by adding 1.1g if sodium ethanoate into 100cm3 of 0.4 moldm-3 of ethanoic acid. Ka =1.7x10-5. What are the steps to calculate the pH? (1) Work out the number of moles ethanoic acid and the number of moles of sodium methanoate. WebbThe pH of the buffer differs from its buffer capacity. The pH range is the range at which the buffer is effective. Typically, buffers have a usable range within 1 pH unit of the pK a of the acid component of the buffer. References.
