You can determine that the acid has completely reacted by observing a change in pH, typically using pH indicators or pH meters. If you're performing a titration, the endpoint is indicated by a color change of the indicator, signaling that the acid has reacted with the base. Additionally, if gas is produced, the cessation of bubbling can also indicate that the reaction has finished. Lastly, monitoring for any other physical changes, such as temperature stability or the formation of precipitates, can also signal completion.
What else can I help you with?
Which acid reacted to give the salt NaCl?
The acid that reacted to give the salt NaCl is hydrochloric acid (HCl).
What would you use to show when an acid has completely reacted with an alkali?
A pH indicator: the color is changed at the end of the reaction, when the solution become alkaline.
How can you tell when the copper has reacted completely and the excess sulfur is burned off?
You can tell when the copper has reacted completely and the excess sulfur is burned off by observing a consistent color change in the reaction mixture. Once the color stops changing, it indicates that the reaction is complete and all the excess sulfur has been consumed.
What is the term for the stage in an acid-base titration when the indicator changes color?
The term for the stage in an acid-base titration when the indicator changes color is called the endpoint. It signifies that the stoichiometric equivalence point has been reached, where the acid and base have reacted completely.
What is carbonic acid mixture of?
Carbonic Acid is water reacted with carbon dioxide.
What happens when a fatty acid is reacted with NaOH?
When a fatty acid is reacted with NaOH, a process called saponification occurs. This reaction results in the formation of soap, which is a salt of the fatty acid alongside glycerol. This reaction is commonly used in soap-making processes.
What happens if you reacted metals with acid?
Hydrogen will be liberated.
Sulphates are made from what acid?
Substances which are reacted with Sulphuric acid tend to produce sulphates.
What acid and alkali can be reacted together to make iron sulfate?
Iron can be reacted with sulfuric acid to produce iron sulfate. Iron sulfate can also be produced by reacting iron with sodium hydroxide and sulfuric acid.
What acid and alkali can be reacted together to make sodium chloride?
hydrochloric acid and sodium hydroxide
What happens when copper is reacted with dilute sulfuric acid?
Copper does not react with dilute Sulphuric acid.
What happens when Na metal is reacted with sulphuric acid?
Na2So4
