Why pH range is not more than 14?
One far end is not more than 1M of hydrogen ions, which results in a pH value of not more than 0. While on the other end is not more than 1M of hydroxide ions which results in a pH value of not more than 14. The pH value goes out of the 0-14 range when the concentration of the solution exceeds 1M.
Which aqueous solution has highest pH?
The other two possibilities for a salt are strong acid and weak base or weak acid and strong base. As we can see, it is a salt of strong acid and strong base and has complete dissociation in water, it is the salt with highest pH. It’s pH will be equal to 7. Hence, the correct option is A.
Which aqueous solution will have the largest poh?
Therefore, 0. 01M NaOH solution has highest pH .
Which aqueous solution will be neutral?
Neutral aqueous solutions are mixtures of water and other chemical compounds with a pH near 7. The chemical compounds may include surfactants, corrosion inhibitors, and other additives. Neutral and alkaline aqueous solutions are the most commonly used aqueous solutions.
Which aqueous solution has the highest boiling point?
Thus, Na3PO4 has the highest boiling point.
Which of the following aqueous solution has highest freezing point?
glucose
