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.
pH is related to the activity of ions H+ in a solution. A pH under 7 is acidic, pH=7 is neutral and a pH over 7 is basic.
zinc nitrate
This compound is zinc nitrate.
The compound Zn(NO₃)₂ is called zinc nitrate. It consists of zinc ions (Zn²⁺) and nitrate ions (NO₃⁻), and is commonly used in fertilizers, as well as in various chemical processes.
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.
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 1 is the most acidic, as it is closest to 0 on the pH scale. Lower pH values indicate higher acidity.
pH=6,4

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.
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.
The pH is determined with a pH-meter.
pH 0 < acidic < pH 7 neutral = pH 7 pH 7 < basic < pH 14
