HELP PLEASE!!!!!!!
You go to a online school. This is a discussion for Social Studies. This question is the topic. Study the textbook.
Analytical Chemistry
A 22.617 g sample of aqueous waste leaving a fertilizer manufacturer contains ammonia. The sample is diluted with 70.407 g of water. A 10.883 g aliquot of this solution is then titrated with 0.1072 M HCl. It required 29.32 mL of the HCl solution to reach the methyl red endpoin...
