What chemical is opposite of an acid?
Bases and Alkalis are the opposites of acids. Alkalis are bases dissolved in water. When combined in the equal quantities, they neutralise each other.
Do all alkalis dissolved in water?
Yes. Water is needed for any alkali to become truly basic, because only then can they accept H+ ions. Remember that bases are proton acceptors.
How can you separate aluminium hydroxide and iron oxide?
If the iron oxide is Fe3O4 you can use a magnet.This is possible because magnetite has strong magnetic properties.For the separation from other iron oxides aluminium hydroxide can be dissolved in alkalis; iron oxides are not soluble in alkalis.
What is the oxygen dissolved in water is a?
The oxygen dissolved in water is a measure of dissolved oxygen (DO).
When all the water evaporates the dissolved materials become what?
desicated

Are all alkalis dissolable?
All alkalis are soluble in water.

If you add alkali to water what colour would the water be?
Alkalis are bases dissolved in water. They do not have specific colours and are often colourless liquids.Indicators are used to determine the strength of an acid or alkali and change colour when exposed to the liquid.Look at Universal Indicator Solution.
Do all alkalis contain oxygen and hyrodrogen?
Yes, all alkalis contain oxygen and hydrogen.
Are all acids disolved in water?
no, not all acids are dissolved in water!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
List four properties of alkalis?
alkalis are corrosive, normally water soluble and are very soapy.
In which all liquid is salt dissolved?
Sodium chloride is easily dissolved in water.
Do all alkalis contain hydrogen and oxygen?
Yes all alkalis have an OH- group, however this is not true for bases.
Do acids react with alkalis?
Yes, that is called a neutralization reaction.
Bases which do not dissolve in water?
Bases are insoluble in water; alkalis are soluble bases.
What do alkalis do when added to acids?
it forms salts and water.
