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.

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 1 is the most acidic, as it is closest to 0 on the pH scale. Lower pH values indicate higher acidity.
pH=6,4
1 atom of Zn (zinc) + 2 atoms of N (nitrogen) + 6 atoms of O (oxygen) = 9 atoms in 1 molecule of Zn(NO3)2.

You can test the pH of a solution using pH strips, pH meters, or pH indicator solutions. With pH strips, you simply dip the strip into the solution and compare the color change to a pH color chart. pH meters provide a digital pH value by immersing the electrode into the solution. pH indicator solutions change color based on the pH of the solution, allowing for a visual estimation of pH.
The pH is determined with a pH-meter.
To measure pH accurately in a solution, you can use a pH meter or pH strips. A pH meter provides a digital reading of the pH level, while pH strips change color based on the pH level of the solution. Simply dip the pH meter probe or pH strip into the solution and read the pH value indicated.
pH 0 < acidic < pH 7 neutral = pH 7 pH 7 < basic < pH 14
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
