Question

5 solution A,B,C,D,E when tested with universal indicator showed4, 1, 11, 7 and 9 respectively which solution is natural,strongly, alkaline, strongly acidic, weakly acidic, weekly alkaline

Answer 1

Solution A- weakly acidic

Solution  B- strongly acidic

Solution C- strongly basic(*acc. to the question)

Solution D- neutral

Solution E- weakly basic

Recall that the value of pH is related to the concentration of H+ ( H3O+ ) of a substance. pH itself is approximated as the cologarithm or negative logarithm of the  H+ ion concentration

Answer 2

A= weakly acidic

B= strongly acidic

C= strong alkaline

D= natural

E= weakly alkaline
