A2.400-g sample of meat is subjected to kjeldahl analysis. the liberated nh3(g) is absorbed by adding 50.00 ml of h2so4(aq), which is more than enough. this occurs through the reaction 2nh3(g)+h2so4(aq)→(nh4)2so4(aq) the excess acid requires 19.90 ml of 0.5510 m naoh for its complete neutralization.
