A certain sample of rainwater gives a yellow colour
P with methyl red [pH range 4.2 (red) -6.2 (yellow)]

W and a yellow colour with phenol red \( [\mathrm{pH} \) range 6.4 (yellow) -8.0 (red)]. What is the approximate \( \mathrm{pH} \) of the water? Is the rainwater acidic, neutral or basic?
(1) 6.3 , acidic
(2) 6.1 acidic
(3) 6.5 , acidic
(4) 6.3 , basic
