In Chemistry Bases (whether strong or weak) are described as Caustic. So depending on the concentration would be greater than pH 7. When the word Caustic used, it is usually associated with a very high pH typically 12- 14.
Raises it
A normal or neutral pH level is 7. Caustic soda is highly basic with a pH of between 13.5 and 15. Caustic soda is a dangerous base and should be handled carefully.
I'm a chemist waste water operator and we use caustic soda to raise pH levels and sulfuric acid to lower pH levels
The PH of neutral is 7 on the scale. Lower is acidic, higher is caustic.
Alkaline means "having a pH between 7.1 and 14". Caustic means harsh, corrosive in some way. Both strong acids and strong bases are caustic.
Items that have a pH of 14 are the least acidic. Caustic soda, cucumbers, radishes, squash, and liquid drain cleaner all have a pH of 14. There are more, obviously, but these are just a few.

Yes, this pH is very alkaline.
yeah, creating a high pH environment (pH>13), caustic kills almost all bacteria.
No you add acid to lower the pH
The PH of neutral is 7 on the scale. Lower is acidic, higher is caustic.
This depends on the desired pH, volume of solution, initial pH, etc.
Caustic NaOH,
A pH of 7 is neutral. Below 7 is acidic and above 7 is caustic.
A cleaner containing caustic soda would be described as basic, and its pH would be low, like 2 or so. Caustic soda is a pretty active (strong) base. Compare this to the pH of a neutral substance, which is 7, or an acid which is greater than 7, and the higher it is, the stronger the acid.
Yes, pH above 7 is the result of a more alkaline, caustic solution. It means that there's more hydroxide ions than hydroxonium ions (or protons) in this.
