When a carbonate reacts with an acid, it forms a salt, carbon dioxide gas, and water. The general chemical equation for this reaction is: carbonate + acid → salt + carbon dioxide + water. This reaction is a type of double displacement reaction, where the carbonate ion (CO3 2-) from the carbonate compound reacts with the hydrogen ion (H+) from the acid to form water and carbon dioxide gas, leaving behind a salt.
Hydrochloric acid and sodium hydroxide yield salt and water H+ + Cl- + Na+ + OH- --> Na+ + Cl- + H2OComment:In solutions you better leave unchanged ions ( Cl- and Na+) out of the balanced equation: called to be 'tribune ions' (people on the tribune don't take part in the 'match'):H+ + OH- --> H2O This looks simpler than: H+ + Cl - + Na + + OH- --> Na + + Cl - + H2O
Not by itself. A cup of salt may be a fraction of the total amount of salt in the world, but just sitting there, a cup of salt is a cup of salt.
It depends on how thinly the salt is spread.
Acid plus metal carbonate typically results in the production of salt, carbon dioxide gas, and water. The chemical reaction between the acid and metal carbonate involves the acid reacting with the metal component of the carbonate to form a salt, while carbon dioxide gas is released as a byproduct.
Metal+Acid=Salt+Hydrogen
When an acid reacts with a base, it forms salt and water. When an acid reacts with a metal, it forms salt and hydrogen gas.
Water
water
When a metal hydroxide reacts with an acid, it forms water and a salt. The metal from the hydroxide forms the cation of the salt, while the anion from the acid forms the anion of the salt. This reaction is known as neutralization.
acid+metal-->salt plus hydrogen
An acid plus a metal produces a salt of the acid plus Hydrogen gas. 2HCl + 2Na ---> 2NaCl + H2
OH(-) A hydroxide. base
When metal reacts with acid, it typically produces a salt and hydrogen gas. The metal displaces the hydrogen in the acid to form a salt and release hydrogen gas. The specific salt formed depends on the type of metal and acid involved in the reaction.
When a metal reacts with an acid, it forms a salt and hydrogen gas. The general equation for this reaction is: metal + acid → salt + hydrogen gas. For example, when sodium reacts with hydrochloric acid, the reaction is: 2Na + 2HCl → 2NaCl + H2.
Only when they exactly neutralise one another.
