Question

pH of 4 solution a ,b ,c and d are 2,7,8 and 6 respectively what is the correct order of acidity of this solution​

Answer 1

Answer:

a>d>b>c is the answer.

Answer 2

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
