write the pH value of:-
1) dilute hydrochloric acid
2) NaOH solution
3) dilute solution of ethanoic acid
4) lemon juice
6) dilute solution of sodium bicarbonate
plzzz... urgent !!
1) Dil HCl = usually it is 1.To know the exact value we need to know the exact concentration.
2)NaOH solution = Stron basic solution .Thus pH is normally above 12.
3)Lemon jucie contains acid like vinegar thus has an approximate pH of 2.4
4)Ethanoic acid = approx pH less than 3
5) Water = neutral has an approx pH 7
6)Sodium bicarbonate = approx 8
Please note to know the exact pH we first need to know the exact concentration.
