2-propanol is also known as isopropanol, and has a neutral pH level of approximately 7, similar to pure water. This is because 2-propanol is an alcohol, and alcohol typically does not disassociate.
PH 75 is the most acid.
pH 9 - pH 4 = pH 5 It is stronger by 5 pH.
Most acidic is substance of pH of 2, then of pH of 5 and the substance of pH 7 is neutral and the substance of pH 11 is basic
The lower the pH, the more acidic the solution is. Remember, pH 7.0 is H2O. As pH decreases below 7, the solution's acidity increases. As pH increase above 7, the basicity of the solution increases. Hence, in the choices you provided, pH 1.0 is most acidic.
pH 0 < acidic < pH 7 neutral = pH 7 pH 7 < basic < pH 14
It is soluble in water, as would be expected (the molecule has a dipole moment), so I would guess that it would be poorly soluble in nonpolar solvents such as hexane or carbon tetrachloride. This is just a guess though...
PH 75 is the most acid.
pH=6,4
pH 9 - pH 4 = pH 5 It is stronger by 5 pH.
neither pH
Most acidic is substance of pH of 2, then of pH of 5 and the substance of pH 7 is neutral and the substance of pH 11 is basic

The pH is determined with a pH-meter.
pH 0 < acidic < pH 7 neutral = pH 7 pH 7 < basic < pH 14
Most probably PH 12, that is if you add 8+4
pH = 14 is basic pH = 7 is neutral pH - 1 and 2 are acidic; pH = 1 is more acidic than pH = 2 Therefore a solution at pH 1 has higher concentration of H+ than at pH 14
