It depends upon the concentration.
Both are strong bases and a solution of either will have a high pH.
No, sodium hydroxide (NaOH) does not have a pH of 7. Sodium hydroxide is a strong base and has a pH greater than 7. The pH of a solution of sodium hydroxide depends on its concentration. A 0.1 M solution of NaOH has a pH of 13.
The pH level of aluminum hydroxide is around 9-10, making it slightly basic.
The pH of ferrous hydroxide can vary depending on its solubility in water. Typically, ferrous hydroxide is considered to be basic in nature and can have a pH range between 8 to 10 when it is formed in a solution.
A substance with a pH of 14 is considered highly basic or alkaline. It indicates a strong concentration of hydroxide ions in the solution. Examples of substances with pH 14 include sodium hydroxide and potassium hydroxide.
The pH of ammonium hydroxide (NH4OH) is typically around 11-12, making it alkaline.
The pH of calcium hydroxide is around 12-13, making it a strong base. It dissociates in water to release hydroxide ions, which gives the solution its high pH value.
As hydroxide ion concentration increases, the pH will increase. This is because hydroxide ions are basic and will consume hydrogen ions, leading to a decrease in hydrogen ion concentration and an increase in pH.
Adding calcium hydroxide to water would raise the pH of the solution. Calcium hydroxide is a strong base and will dissociate in water to increase the concentration of hydroxide ions, leading to an increase in pH.
A solution of sodium hydroxide in water will have a pH close to 14, as sodium hydroxide is a strong base that dissociates completely in water to produce hydroxide ions, increasing the pH.
Sodium hydroxide is alkaline and so its pH must be above 7. It is not a strong base so its pH may be 9 approximately.
Radium hydroxide is a strong alkaline compound, so it would have a high pH value. However, the exact pH would depend on the concentration of the radium hydroxide solution.
