What is the color of the indicator when an excess of hydrochloric acid has been added?
The indicator turns pink when an excess of hydrochloric acid has been added in a titration.
What colour will the indicator turn when the right amounts of acid and alkali have been combined to make a solution of salt and water?
The indicator will turn green when the right amounts of acid and alkali have been combined to make a solution of salt and water. This indicates that the solution has reached a neutral pH level.
What happens when acid and alkali react?
When an acid and alkali react, they neutralize each other to form water and a salt. The reaction involves the transfer of protons from the acid to the alkali. The resulting solution will be closer to neutral pH.
How can you tell when as excess of hydrochloric acid has been added to the evaporating dish with the magnesium?
When excess hydrochloric acid has been added to an evaporating dish with magnesium, you will observe bubbling and fizzing as the magnesium reacts with the acid. Once all the magnesium has been consumed in the reaction, no more bubbles will be produced, indicating that excess acid is present.
Why water may be added after the acid has been pipetted in?
Adding water after the acid can help to dilute the acid in a controlled manner, minimizing any splashing or spattering that may occur if water were added to the acid. This step also allows for better mixing of the acid and water to ensure uniformity in the solution.

What happens if the green antifreeze has been added?
turnes in to acid..
What is percentage purity of sulfuric acid?
It depends on what has been added or how dilute it is.

What is the procedure to neutralizing an acid?
Add an alkali. Remember the general chemical reaction Acid + Alkali = Salt + Water. However, if the acid has been ingested by a human, then give a carbonate, because the 'raw' alkali can also do damage to a human. The chemical reaction of a carbonate is Acid + Carbonate = Salt + Water + Carbon Dioxide(burp!!!). Common carbonates are sodium bi-carbonate(baking powder). or proprietary medicnes such as 'Milk of Magnesia' Milk of magnesia is a suspension of magnesium carbonate and magnesium hydroxide. .

Adding water after the acid can help to dilute the acid in a controlled manner, minimizing any splashing or spattering that may occur if water were added to the acid. This step also allows for better mixing of the acid and water to ensure uniformity in the solution.
When just enough acid has been added to neutralize the sodium hydroxide what colour will the indicator be?
The indicator will change color to indicate when just enough acid has been added to neutralize the sodium hydroxide. For example, phenolphthalein will turn colorless in an acidic solution, indicating that the base has been neutralized.
What has recently been added to bread and other grains in effort to reduce birth defects?
Folic Acid
Why the Erlenmeyer flask does not have to be dry and why water may be added after the 25.00-centimetre Cube of Acid has been pipetted in?
?
How can you neatralise acid?
One way to neutralize acid is by adding a base, which will react with the acid to form water and a salt. This reaction will decrease the acidity of the solution by balancing the concentrations of hydrogen ions and hydroxide ions. Additionally, using a pH indicator can help determine when the acid has been fully neutralized.
