Acetic acid is added in the limit test for sulphates to prevent the precipitation of other metal ions that could interfere with the test results. It forms a soluble complex with various metal ions, ensuring that only sulphates are precipitated and measured accurately.

Sulphates are made from what acid?

Substances which are reacted with Sulphuric acid tend to produce sulphates.


What happens if magnesium ribbions is added in acetic acid?

When magnesium ribbon is added to acetic acid, a chemical reaction occurs which produces hydrogen gas and magnesium acetate. The magnesium ribbon will dissolve as it reacts with the acetic acid, releasing bubbles of hydrogen gas in the process. This can be observed by the fizzing or bubbling that occurs.


Can acetic acid and water mix?

Yes, acetic acid is highly soluble in water.


What colour is produced when universal indicator is added to acetic acid?

When universal indicator is added to acetic acid, it typically turns a shade of red, indicating that the solution is acidic. Acetic acid is a weak acid, so the color change may not be as intense as with stronger acids.


Why is acetic acid added in the preperation of glucosazone?

Acetic acid is added in the preparation of glucosazone to help maintain the acidic conditions needed for the reaction to occur. It also helps to stabilize the product and prevent decomposition. Additionally, acetic acid can act as a catalyst in the formation of glucosazone.


When red litmus is added to acetic acid what will be the colour of litmus paper?

The red litmus paper will remain red in acetic acid. Acetic acid is a weak acid and does not change the color of red litmus paper.


Why hcl used in the limit test of sulphates?

Hydrochloric acid (HCl) is used in the limit test of sulphates because it helps in the precipitation of sulphates as insoluble barium sulphate (BaSO4). This makes it easier to quantitatively determine the amount of sulphate present in a sample through gravimetric analysis. The addition of excess HCl ensures that all sulphates are converted to BaSO4, allowing for accurate measurement.


When zinc powder added to acetic acid?

When zinc powder is added to acetic acid, a chemical reaction occurs in which zinc reacts with the acetic acid to produce zinc acetate and hydrogen gas. This reaction is represented by the equation: Zn + 2CH₃COOH → Zn(CH₃COO)₂ + H₂.


Which is more rapid in terms of gas evolution hydrochloric acid added with aluminum or acetic acid added with aluminum?

Hydrochloric acid added with aluminum evolves gas more rapidly compared to acetic acid added with aluminum. This is because hydrochloric acid reacts more vigorously with aluminum, producing hydrogen gas at a faster rate due to the stronger acidic nature of hydrochloric acid.


What will be form in combining acetic acid and water what kind of solution is it?

It will be an aqueous acetic acid solution. normally water is added in order to decrease the concentration of an acid & gives the diluted form of it.


How much acetic acid does soda have?

Soda contains carbonic acid and phosphoric acid, but it does not contain acetic acid.


Why does acetic acid and vinegar not mix well?

Acetic acid is the main component of vinegar. When acetic acid is added to vinegar, it can form layers or droplets due to differences in densities, polarities, or compositions, which can prevent them from mixing well. Additionally, acetic acid is a weak acid, so it may not readily dissolve in water or other components of vinegar.
