sodium and chlorine (Na and Cl) chemically combine
This is a neutralization reaction; the product is a salt.
When an acid is mixed with an alkali, a neutralization reaction occurs. This reaction results in the formation of water and a salt. The acidity of the acid decreases and the alkalinity of the alkali decreases as they react with each other.
When a carbonate, such as calcium carbonate, reacts with an acid, such as hydrochloric acid, it undergoes a chemical reaction and produces carbon dioxide gas, water, and a salt. The reaction can be represented by the general equation: Carbonate + Acid -> Carbon Dioxide + Water + Salt.
If a reaction produces an insoluble salt, you will observe the formation of a cloudy or precipitate solution in the test tube. This indicates that a chemical reaction has occurred and a solid salt has been formed that is not soluble in the reaction mixture.
A salt is a type of chemical compound, not a reaction.
When limestone reacts with acid, it undergoes a chemical reaction that produces carbon dioxide gas, water, and a salt. This reaction is called neutralization and can be represented by the equation: CaCO3 + 2HCl -> CO2 + H2O + CaCl2.
When citric acid and carbonate mix, a chemical reaction occurs that produces carbon dioxide gas, water, and a salt. This reaction is commonly used in effervescent tablets and in baking as a leavening agent.
It is commonly called 'neutralisation' and the resultant chemical compounds are 'a salt' and 'water'.
When you heat salt (sodium chloride), it undergoes a physical change rather than a chemical change. The heat causes the salt crystals to break apart and melt into a liquid state. Upon cooling, the liquid salt will solidify back into crystals.
When vinegar (acidic) and baking soda (basic) are mixed together, a chemical reaction occurs that produces carbon dioxide gas, water, and a salt. This reaction causes fizzing and bubbling as the gas is released.
When iron reacts with acid, it undergoes a chemical reaction that produces hydrogen gas and forms iron salt. The reaction will result in the release of energy in the form of heat. It is important to handle this reaction carefully, as it can be exothermic and may produce flammable hydrogen gas.
When an acid reacts with a carbonate, it produces carbon dioxide gas, water, and a salt. The general chemical equation for this reaction is: acid + carbonate → carbon dioxide + water + salt.
