write the pH value of:-

1) dilute hydrochloric acid

2) NaOH solution

3) dilute solution of ethanoic acid

4) lemon juice

5) water

6) dilute solution of sodium bicarbonate

plzzz... urgent !!

pH of 
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.
