The zinc nitrate solution is acidic.
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.
zinc nitrate
This compound is zinc nitrate.
Is Zn(NO3)2 is soluble or insoluble?The answer is soluble, it can dissolve in water.In general, simple metal nitrates are almost always soluble.
PH 75 is the most acid.
1 atom of Zn (zinc) + 2 atoms of N (nitrogen) + 6 atoms of O (oxygen) = 9 atoms in 1 molecule of Zn(NO3)2.
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
