Thanks ?
\tBasisAcidBaseDefinitionAn acid is any chemical compound once dissolved in water produces a solution with hydrogen ion activity more than purified waterA base is an aqueous substance that could absorb hydrogen ions.StrengthRelies on the concentration of the hydronium ionsRelies on the concentration of the hydroxide ionsExamplesAcetic acid CH3COOH and\xa0sulphuric acidSodium Hydroxide (NaOH) and AmmoniaCharacteristics (Physical)Would depend upon the temperature acids would look solid, liquid or in the form of gas. It would also have a sour taste.Bases would feel slippery and solid in nature (except for ammonia, which is gaseous). It would have a bitter taste.DisassociationAcids would release hydrogen ions (h+) when mixed with waterBases would release hydroxide ions(OH-) when mixed with waterTest with LitmusWould turn litmus paper redWould turn litmus paper blue\t
Acid are the sour substances that turn blue litmus red and they have a lower ph value they give out H+ ions in water Whereas Bases are the substances that are bitter in taste they turn red litmus blue and they have high ph value they give out OH-ions in aqueous solution
Acid is sour in taste and Base is bitter to taste.Acid may cause burn but base feels soapy to touch.
