The concentration of hydroxide ion of a solution with a pH of 8. 25 is 1.77×
M
Calculation,
The pH of a solution tells us about concentration of the 
ion ( proton ) in solution. However, if we know the value of pH , we can calculate pOH with the help of pH and from pOH we can find concentration of hydroxide ions in the solution.
pH + pOH = 14
8. 25 + pOH = 14
pOH = 14 - 8. 25 = 5.75
Since, pH = -㏒[ ]
Similarly, pOH = -㏒[
]
If pOH = 5.75 , that means that -㏒[ ] = 5.75 ,which means that,
[ ] = 
= 1.77×.
So, we know that the concentration of the ions in the solution with pH of 8.25 is 1.77× Molar

Answer:
It is like an arch because it bends horizontal just like we do and the legs of the arch support the stone like our feet and legs support the weight of us.
Explanation:
Phenolphthalein turn pink in basic solutions.it turn colourless in acid solution.
Hence options(1)is correct
