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
dycal is made of calcium hydroxide which helps regenerate the dentin & protects the pulp
PH 75 is the most acid.
pH=6,4
pH 9 - pH 4 = pH 5 It is stronger by 5 pH.
calcium hydroxide topical solution is used in prepearing various astringent formulations for topical application to the skin and mukous membranes.
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 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.
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
