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

They are electrically neutral, they are not deflected by magnetic fields
A liquid with high viscosity does not flow easily and is not effective in wetting a surface.
When a metal is subjected to corrosive elements including salt, moisture, and high temperatures, a reaction called corrosion takes place inside the metal. Some foods contain metallic compounds that can corrode a material. The majority of corrosion is simply surface dis-colouration, which polishing agents may quickly remove.
Increasing viscosity and constant intermolecular water bonding together result in surface tension. Any liquid that was more viscous than water possessed a surface tension that was equal to or lower than that of water. Viscosity with surface tension decrease when temperature rises.
Therefore, a liquid with high viscosity does not flow easily and is not effective in wetting a surface.
