Question

4student a b c and d have been given solution with PH 379 and 13 respectively has the students in first identify the most basic and most acidic solution second arranging the four solutions in a decreasing order of h + iron concentration ​

Answer 1

Answer:

The highest pH values are shown by bases while the acids give low values on pH scale.Sodium bicarbonate is a strong base with pH value greater than 7, water is neutral with pH 7 while acids like lemon juice have pH value less than 7 on a pH scale of 14. So, the decreasing pH order is (sodium bicarbonate > water > lemon juice).
