We need 1.00 L of a formic acid/formate (Ka= 1.80x10-4) buffer with a starting pH of 3.500. It must be able to resist the addition of 20.00 mL of 0.250 M NaOH while remaining below pH 4.150. How many mL of 0.500 M stock acid and 0.250 M NaOH base solution must be used in preparation of this buffer? Check both answers.
25 g of a certain metal is heated in boiling water and then poured into 90 mL of water initially at 22.0oC. After the water has resumed a constant temperature.
