What is the approximate ph at the equivalence point of a weak acid-strong base titration if 25 ml of aqueous formic acid requires 29.80 ml of 0.3567 m naoh? ka =1.8 × 10-4 for formic acid.

24. a sports ball is inflated to an internal pressure of 1.85 atm at room temperature (25 °c). if the ball is then played with outside where the temperature is 7.5 °c, what will be the new pressure of the ball? assume the ball does not change in volume nor does any air leak from the ball a) 0.555 atm b) 1.74 atm c) 1.85 atm d) 1.97 atm
