Determine which of the following statements are True or False about 500.0 mL of buffer consisting of 0.70 M butanoic acid (HC4H7O2) and 0.85 M sodium butanoate (NaC4H7O2): The pH slightly increases when 25.0 mL of 0.25 M sodium hydroxide is added to the buffer but the buffer is still effective 0.150 moles of hydrochloric acid will be neutralized by butanoic acid and the buffer will still be effective 0.220 moles of sodium hydroxide will be neutralized by butanoic acid and the buffer will still be effective
