How do you make concentrated sulfuric acid from dilute sulfuric acid?
You need to remove the water by evaporation.
Does hydrochloric acid need air to react with iron?
No, hydrochloric acid does not need air to react with iron. When hydrochloric acid reacts with iron, you will notice the reaction because of the bubbling.
Why sulfuric acid is mineral acid?
All the reactants that need in manufacturing of sulfuric acid are in nature, any of them are not synthesized manually.
Why is sulphuric acid added with a measuring cylinder?
- because sometimes we need to know exactly the volume of sulfuric acid - also because sulfuric acid is corrosive and dangerous
How much ml 10 percent lime milk do you add in sulfuric acid to get pH 4?
You need to add a bit of lime milk to get sulfuric acid to pH 4.
What type of acid do you need to melt metal?
Acids don't actually melt metal, they oxidize or corrode them. Usually producing the corresponding metal salt and hydrogen gas. Most strong acids (hydrochloric, hydrobromic, hydroiodic, perchloric, nitric, and sulfuric acids) will oxidize metals in this manner. Some weak acids such as hydrofluoric acid can oxidize metals. Some metals, such as the alkali metals and alkaline earth metals will react with virtually any acid and even water. Nitric acid can oxidize copper, which normally doesn't react with acid. Aqua regia, a mixture of nitric acid and hydrochloric acid will oxidize gold and platinum, which are usually considered immune to corrosion.

Why do you need sulfuric acid?
by being a don

Can you use lemon juice as simulated stomach acid?
No the pH level of acid is too less. Everyone has HCl (hydrochloric acid) + some bacteria in their stomachs, so you need to collect enzymes from bacteria and a strong acid like Hydrochloric acid or sulfuric acid.

Why is chlorine necessary for digestion?
We need chlorine to help form hydrochloric acid in our stomachs because chlorine is a part of the element of hydrochloric acid
How many points in one liter?
If you need (for example) three parts water and one part hydrochloric acid, that just means you need a 3:1 ratio of water to hydrochloric acid. It could mean three liters of water and one liter of hydrochloric acid, three mL of water and one mL of hydrochloric acid, three cups of water and one cup of hydrochloric acid, etc.
How much ml 10 percent lime milk do you add in sulfuric acid to get pH 4?
You need to add a bit of lime milk to get sulfuric acid to pH 4.
Can you make hydrochloric by combining Sulfuric acid and table salt....do i need any special lab equipment or something like that.?
It is possible, BUT VERY HAZARDOUS OUTSIDE A LABORATORY, to make hydrogen chloride gas by reacting solid salt with sulfuric acid. Hydrogen chloride gas is very dangerous to breathe and can burn skin; you should NOT perform this without adequate ventilation and protective equipment!
