1.	Five solutions A, B, C, D and E when tested with universal indicator showed pH as 4, 1, 11, 7 and 9, respectively. Which solution isa) neutral?b) strongly alkaline?c) strongly acidic?d) weakly acidic?e) weakly alkaline?Arrange the pH in increasing order of hydrogen-ion concentration.
Answer» a) Neutral ➝ solution D ➝ pH value of pH is 7. b) strongly alkaline ➝ solution C ➝ pH is 11 c) strongly acidic ➝ solution B ➝ pH is 1 d) weakly acidic ➝ solution A ➝ pH is 4 e) weakly alkaline ➝ solution E ➝ pH is 9 We can arrange the pH in increasing order of hydrogen ion concentration as 11 < 9 < 7 < 4 < 1
