Question

what do you understand by PH value? two solutions X and Y have pH
values of 4 and 10 respectively which one of these two will give a
pink colour with phenolphthalein indicator

Poonam Koijam · Answer

pH?stands for power of hydrogen, which?is ?a measurement of the
hydrogen ion concentration in the body The total?pH?scale ranges
from 1 to 14, with 7 considered to be neutral A?pH less than 7?is
?said to be acidic and solutions with a?pH?greater than 7 are basic
or alkaline
It is given that solution X have 4 pH value and Y have 10 value
We know that phenolphthalien turns pink in basic solutio so
solution Y will turn pink because its pH value is 10 and it is
basic in nature
