Question

(d) It is a solution of phenolphthal
Arrange the following in increasing order of
their pH values ethanoic acid,
acid, sodium
bicarbonate solution and water:
a) ethanoic acid, water, sodium bicarbonate
b) water, ethanoic acid, sodium bicarbonate
-) sodium bicarbonate, ethanoic acid, water
1) water, sodium bicarbonate, ethanoic acid​

Answer 1

Answer:The highest pH values are shown by bases while the acids give low values on pH scale.Sodium bicarbonate is a strong base with pH value greater than 7, water is neutral with pH 7 while acids like lemon juice have pH value less than 7 on a pH scale of 14. So, the decreasing pH order is (sodium bicarbonate > water > lemon juice).

hope this helps you if yes please mark it as brainlist please
