If you're asking what a person's pH is (blood), its about 7.4. For most mammals, its 7.4.
There are certain respiratory and metabolic disorders that can change the pH. If the pH is higher than 7.4, the condition is called alkalosis. If a person's pH is lower than 7.4, its called acidosis.
pH=6,4
The pH of tomato ketchup is 3.85
We can use a pH paper.
The optimum pH of lactase is pH = 6.5.
The higher the pH, the more basic, so a pH of 8 is more basic than a pH of 6.
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 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
pH indicator, pH paper, and a pH meter. You can find them on this page http://onsager.bd.psu.edu/halmi/chem3pHS05.pdf
pH = -log(Concentration)pH = -log(3)pH = -(0.477121255)pH = -0.477121255
