Question

plzz tell answer of this I'll mark 1st and right answer as brainlist ​

Answer 1

Answer:

1)Which solution below has the highest concentration of hydroxide ions?

a. pH= 3.21

b. pH= 7.00

c. pH= 7.93

d. pH= 12.59

2)So here the concentration of hydroxide ions would be 0.200 molar, so as a result, the compound that has the greatest concentration of hydroxide ions is the barium hydroxide, therefore will be the most basic. Remember basicity deals with the concentration of OH-, and acidity deals with the concentration of H+ ion.
