Answer» Bases are bitter in taste Acid are generally sour in taste General Properties of Acids\tAcids are corrosive in nature.\tThey are good conductors of electricity.\tTheir pH values are always less than 7.\tWhen reacted with metals, these substances produce hydrogen gas.\tAcids are sour-tasting substances.\tExamples: Sulfuric acid (H2SO4), Hydrochloric acid (HCl), Acetic acid (CH3COOH).General Properties of Bases\tThey are found to have a soapy texture when touched.\tThese substances release hydroxide ions (OH– ions) when dissolved in water.\tIn their aqueous solutions, bases act as good conductors of electricity.\tThe pH values corresponding to bases are always greater than 7.\tBases are bitter-tasting substances which have the ability to turn red litmus paper blue.\tExamples: Sodium hydroxide (NaOH), milk of magnesia (Mg(OH)2), calcium hydroxide (Ca(OH)2). |
