What ratio of acid to water would you use to dilute 18M sulfuric acid to 6M?

To dilute 18M sulfuric acid to 6M, you would need to use a 1:2 ratio of acid to water. This means mixing 1 part of sulfuric acid with 2 parts of water. For example, you could mix 1 L of 18M sulfuric acid with 2 L of water to get a final concentration of 6M sulfuric acid.

What is the reaction when gold and sulfuric acid are mixed?

Gold is one of the least reactive metal. When gold is mixed with acid, it does not react or dissolve. Gold reacts only with AQUA REGIA [three parts of concentrated hydrochloric acid and one part of nitric acid.] AQUA REGIA can dissolve almost all metals.


How can you obtained an acidic part of an ester?

An acidic part of an ester can be obtained by hydrolyzing the ester with an acid, such as hydrochloric acid or sulfuric acid. This reaction breaks the ester bond, yielding the parent carboxylic acid and alcohol.


What is the ph number for sulphric acid?

The pH value of any acidic solution depends on the strength of the acid in the particular solution. In this instance, a dilute sulfuric acid solution shows a higher value of pH whereas the concentrated acid shows a very low value.


What are some common acids?

Common household acids include citric acid (orange and grapefruit juice), acetic acid (vinegar), carbonic and phosphoric acid (sodas and soft drinks), and hydrochloric acid (formed by mixing vinegar and salt in salads). Tartaric acid is in bananas and grapes, and is important in the fermentation of wine. Formic acid is part of the reason that ant bites hurt. Sulfuric acid is used in car batteries. Common laboratory acids include hydrochloric acid (HCl), sulfuric acid (H2SO4), nitric acid (HNO3), and hydrofluoric acid (HF).
