Question

Which one represents the correct decreasing order of pH values of the samples?

A. Water > Fruit juice > Sodium bicarbonate

B. Sodium bicarbonate > Water > Fruit juice

C. Fruit juice>Water>Sodium bicarbonate

D. Water>Sodium bicarbonate>Fruit juice

ANSWER CORRECTLY !!​

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).
