The solution gets hot
When concentrated sulfuric acid is added to coconut water, the acid will likely react with the components of the coconut water, such as sugars and organic compounds, causing a chemical reaction. This reaction can lead to the production of heat, gas, or changes in color. It is important to handle concentrated sulfuric acid with care as it is a strong acid and can cause burns or release harmful fumes.
The black substance produced when concentrated sulfuric acid is added to sugar is called carbon.
The fizzing will be most when zinc is added to dilute sulfuric acid, as it is a stronger acid that can react more vigorously with the zinc. The fizzing will be least when zinc is added to acetic acid, as this acid is weaker and will not react as vigorously with the zinc.
When sulfuric acid is added to water, it dissociates into hydrogen ions and sulfate ions. This process releases heat, so it is important to add the acid to water slowly and with stirring to prevent splashing or overheating. Additionally, diluting sulfuric acid with water helps to reduce the acidity and make it safer to handle.
When lead acetate is added to concentrated sulfuric acid, a reaction occurs that forms lead sulfate and acetic acid. Lead sulfate is insoluble and will precipitate out of solution. This reaction is typically used to test for the presence of sulfate ions in a solution.

copper sulphate and hydrogen is released.
Sulfuric acid is a strong mineral acid that can react with phenolphthalein, which is a pH indicator. In the presence of sulfuric acid, phenolphthalein can turn colorless due to the acidic conditions. This color change occurs because the sulfuric acid donates protons to the phenolphthalein molecule, changing its structure and causing it to lose its pink color.
The black substance produced when concentrated sulfuric acid is added to sugar is called carbon.
When zinc is added to dilute sulfuric acid in a test tube, a chemical reaction occurs where zinc reacts with sulfuric acid to form zinc sulfate and hydrogen gas. This reaction is a redox reaction where zinc is oxidized to zinc ions, while hydrogen ions in the sulfuric acid are reduced to form hydrogen gas. The production of hydrogen gas can be observed as bubbles forming in the test tube.

The fizzing will be most when zinc is added to dilute sulfuric acid, as it is a stronger acid that can react more vigorously with the zinc. The fizzing will be least when zinc is added to acetic acid, as this acid is weaker and will not react as vigorously with the zinc.
When you add iron fillings to sulfuric acid, a chemical reaction occurs that results in the formation of iron sulfate and hydrogen gas. The iron sulfate typically appears as a green solution, while bubbles of hydrogen gas are released. This reaction is exothermic, meaning it produces heat.

When lead acetate is added to concentrated sulfuric acid, a reaction occurs that forms lead sulfate and acetic acid. Lead sulfate is insoluble and will precipitate out of solution. This reaction is typically used to test for the presence of sulfate ions in a solution.

The "N" in 18 N sulfuric acid stands for normality, which is a unit of concentration used in chemistry. It indicates the number of equivalents of an acid or base per liter of solution. In the case of 18 N sulfuric acid, it means the solution contains 18 equivalents of sulfuric acid per liter.
