Question

the ph of five solutions A, B, C, D and E are 3,7, 10, 5 and 9 respectively. arrange the following solutions in increasing order of hydronium ion concentration.​

Answer 1

Answer:

a) D is neutral, as its pH value is equal to 7 

b) C is strongly alkaline, as its pH value is 11. 

c) B is strongly acidic, as its pH value is equal to 1 

d) A is weakly acidic, as its pH value is equal to 4 and more than solution B. 

e) E is weakly alkaline, as its pH value is equal to 9 and less than C. 

pH value of the given solution in increasing order of hydrogen-ion concentration: 11<9<7<4<1
