When chlorine reacts with water, the resulting solution is weakly acidic and reacts with AgNO 3 to give a white precipitate. The balanced equation to represent these reactions has to be written Why the manufacturers of household bleaches add bases such as NaOH to their products to increase their effectiveness has to be explained Concept Information: A chemical substance that gives hydrogen ions when dissolved in water is called as acid. A chemical substance that gives hydroxide ions when dissolved in water is called as base. Acid and base undergoes many chemical reactions which are useful in our day to day life. To write: The balanced equation to represent the above reactions To Explain: Why the manufacturers of household bleaches add bases such as NaOH to their products to increase their effectiveness
