Question

you have 3solutions A,B,C whose pH is value is 4,7&10 respectively out of above solution which solution is basic​

Answer 1

solution- B and C of pH 7 , 10 are basic and solution- A of pH 4 is highly acidic .

As ,

A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6.
