How do bases react with metals

These are also known as alkali. For example: sodium hydroxide, magnesium hydroxide, calcium hydroxide, etc. Alkali is considered as strong base. Example: Sodium hydroxide gives hydrogen gas and sodium zincate when reacts with zinc metal.

Non-metal oxides are acidic in nature. For example; carbon dioxide is a non-metal oxide. When carbon dioxide is dissolved in water it produces carbonic acid. Therefore, when a base reacts with non-metal oxide both neutralize each other resulting production of salt and water.

Example: Sodium hydroxide gives sodium carbonate and water when it reacts with carbon dioxide. Since in the reaction between acid and base both neutralize each other, hence it is also known as neutralization reaction. Example: Sodium chloride and water are formed when hydrochloric acid reacts with sodium hydroxide a strong base. In similar way, calcium chloride is formed along with water when hydrochloric acid reacts with calcium hydroxide a base.

Salt solutions do not always have a pH of 7, however. Through a process known as hydrolysis , the ions produced when an acid and base combine may react with the water molecules to produce a solution that is slightly acidic or basic.

As a general concept, if a strong acid is mixed with a weak base, the resulting solution will be slightly acidic. If a strong base is mixed with a weak acid, the solution will be slightly basic. Calcium propionate is used to inhibit the growth of molds in foods, tobacco, and some medicines.

This is a double displacement reaction, so the cations and anions swap to create the water and the salt. Write a balanced chemical equation for the reaction of solid barium hydroxide with dilute acetic acid.

Acids react with most metals to form a salt and hydrogen gas. As discussed previously, metals that are more active than acids can undergo a single displacement reaction. For example, zinc metal reacts with hydrochloric acid, producing zinc chloride and hydrogen gas. Bases also react with certain metals, like zinc or aluminum, to produce hydrogen gas. For example, sodium hydroxide reacts with zinc and water to form sodium zincate and hydrogen gas.
