can you please explain the last part about the cleaner that uses biggest volume of acid has highest concentration
@soselozi3805 3 ай бұрын
So like basically, the higher the concentration of ammonia in the cleaner, the more volume of acid it will need to reach an end point so that the indicator changes colors. So the cleaner that needs more acid to reach said end point is the cleaner with higher concentration of ammonia
