What do salts produce when heated?

- some salts as NaCl can be melted - other salts as Na2CO3 are thermally decomposed, obtaining a metal oxide


Is indium toxic?

No. Not the metal itself but some of its salts and compounds are.


How do you make salts by metals?

Salts are typically formed by the reaction of a metal with an acid. The metal reacts with the acid, displacing the hydrogen and forming a salt and hydrogen gas. The type of salt formed depends on the metal and acid used in the reaction.


What salts does sulfuric acid make?

Sulfuric acid can form salts by reacting with metals, metal oxides, metal hydroxides or metal carbonates. Some common salts produced from sulfuric acid include sulfates such as sodium sulfate (Na2SO4), copper sulfate (CuSO4) and zinc sulfate (ZnSO4).


Is gallium an organic material?

Gallium is a metal, symbol Ga it is in group 13 (group III) The name is easily confused with the organic compound gallic acid whose "proper" name is 3,4,5-trihydroxybenzoic acid. It gets more confusing as some chemists call some salts of gallium, "gallates" which is what salts of gallic acid are called.


What is the colour of ammonium salts?

Ammonium salts can come in various colors, but many are white or colorless in their pure form. Some may have a slightly yellow or brown tint depending on impurities present.


Are the bright light emission spectra different or similar for the metal salts?

The bright light emission spectra of different metal salts can vary significantly due to the unique electronic structures and energy levels of the metal ions involved. Each metal salt will produce distinct emission lines corresponding to the specific wavelengths of light emitted when electrons transition between energy levels. However, some metal salts may exhibit similar spectral features if they contain metal ions from the same group or have similar electronic configurations. Overall, while there can be similarities among certain groups, the emission spectra are generally distinct for different metal salts.


How are minerals related to salts?

Salts are compounds that are formed when a metal cation combines with a non-metal anion. Minerals, on the other hand, are naturally occurring inorganic substances that have a fixed chemical composition and crystal structure. Some minerals, such as halite (salt), are composed of salts.


What happens to a metal when exposed to an acid after three days?

The metal may undergo a chemical reaction with the acid, leading to corrosion or the formation of metal salts. This process can result in the metal surface being damaged or weakened, depending on the type of metal and concentration of the acid.


Inorganic calcium salts?

Some calcium salts are organic, some calcium salts are inorganic.


What is action of heat on salts?

Heating salts can cause them to undergo various reactions. Some salts may decompose, forming a metal oxide and a gas. Other salts may melt or dissolve, depending on their chemical composition. Additionally, heating salts can sometimes change their color due to the formation of new compounds.
