2 L of an unknown concentration of the weak base ammonia are standardized. 50.0 mL of the basic solution are titrated with 0.200 M HCl. The end point occurs after 86.8 mL of acid are added. What is the concentration of ammonia in the 2 L flask

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. they do not involve measurements or numbers. for instance, colors, shapes, and textures of objects are all qualitative observations.
