Question

Rajat and Ashima have got two different solutions A and B respectively. The concentration of hydronium ion is more in case of solution A.Solution B turns pink in the presence of phenolphthalein while A turns the colour of pH paper orange.The pH of solutions A and B can respectively be—a)7,13 b)13,14 c)2,14 d)14,13 Ashima have got two different solutions A and B respectively the concentration of hydronium ion is more in case of solution solution be turns pink in the presence of character in violet and the colour of PH paper Orange the pH of solution A and B can be respectively be

Answer 1

bhai i do not know na sorry bhai

Answer 2

By general definition solutions having high replaceable hydronium concentration can be called acid. Here sol. A has more h3o+ concentration than sol. B; and sol.A turns pH paper orange. If we look at the pH colour range of pH paper, it can be concluded the pH of sol. A is 2.

Sol. B , as it turns pink in presence of phenolphthalein it is basic, we can't tell a sharp pH of sol. B but by the options; it is 14. And the correct option is c)2,14.

I can't understand the second part.
