What are substances that remove H from a solution?
Substances that remove H+ ions from a solution are called bases or alkalis. Bases react with H+ ions to form water, reducing the concentration of H+ ions in the solution. Examples of bases include sodium hydroxide (NaOH) and ammonia (NH3).
Are acids and alkalis the same?
No, acids and alkalis are not the same. Acids are compounds that release hydrogen ions when dissolved in water, whereas alkalis are compounds that release hydroxide ions when dissolved in water. Acids have a pH less than 7, while alkalis have a pH greater than 7.
What is the solution called when it has no ions?
A solution without ions is called a nonionic solution. This means that the solute molecules in the solution do not dissociate into charged particles like ions.
A base donates what ions into solution?
A base donates hydroxide ions (OH-) into solution.
Magnesium ribbon is put into blue copper sulphate solution the solution becomes colourless and a pinkish metal is produced?
When magnesium ribbon is put into a blue copper sulphate solution, a single displacement reaction occurs. The magnesium displaces the copper ions, forming magnesium sulfate and elemental copper. The blue color of the solution fades because copper ions are removed and the pinkish metal produced is the elemental copper that settles at the bottom of the container.
