All alkalis are soluble in water.
Bases are not called alkalis. Alkalis are a specific subset of bases that are soluble in water. All alkalis are bases, but not all bases are alkalis.
No, not all alkalis contain oxygen and hydrogen. Alkalis are compounds that contain hydroxide ions (OH-) and can include elements like sodium, potassium, or calcium. These alkalis do not always contain both oxygen and hydrogen in their chemical composition.
No, not all alkalis contain hydrogen and oxygen. Alkalis are a group of chemicals that have a pH greater than 7 and typically contain a hydroxide ion (OH-). Some common examples of alkalis include sodium hydroxide (NaOH) and potassium hydroxide (KOH), which do contain hydrogen and oxygen.
All alkalis contain the hydroxide ion (OH-). This hydroxide ion is responsible for the characteristic properties of alkalis, such as their ability to neutralize acids and their ability to turn litmus paper blue.
No- hydrochloric acid is an acid and is the opposite of an alkali so no alkalis contain it
Yes, they do.
don't you mean dangerous
Yes, an alkali is a type of base that dissolves in water to produce hydroxide ions. So, all alkalis are bases, but not all bases are alkalis.
No, not all alkalis contain hydrogen. Alkalis are a class of compounds that are bases and typically contain hydroxide ions (OH-). Examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH), which do not contain hydrogen on their own.
maybe
alkalis are corrosive, normally water soluble and are very soapy.
They are alkalis, such as sodium carbonate, used by industries, such as glassmakers.
