Answer: The pH of the substance is 8.25. The solution is basic.
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydronium ion concentration. The acids have pH ranging from 1 to 6.9 , salts have pH of 7 and bases have pH ranging from 7.1 to 14.
Putting in the values:
Thus as pH is more than 7, the solution is basic.
The pH of the substance is 8.25. The solution is basic.
The ranking of terms importance in deciding on the true structure of a molecule:
Experimental evidence> Lewis structure> formal charge
- In describing the structure of the molecule experimental evidence is of utmost importance followed by lewis structure and then formal charge.
- Experimental evidence is an inference of a practical technique that one will conduct to determine the original arrangement of atoms in a molecule by following a set of ordered steps.
- Evidence will give the real picture regarding the structure of the molecule as no guesswork or prediction is employed.
- Whereas Lewis structures and formal charge are the theoretical concepts that will only help in predicting the structure of a molecule which can be correct, partially correct, or wrong.
So, from this, we can conclude that the ranking of terms importance in deciding on the true structure of a molecule:
Experimental evidence> Lewis structure> formal charge
