Answer:
A pH scale reading 13 indicates a strong base.
Explanation:
From my understanding:
1 -4 is a strong acid
4 - 7 is weak acid
7 - 9 is a weak base
9 - 14 is a strong base
CO2 ; H20- They are the only ones that, on both sides, combined with another element and bonding of atoms
<u>Answer:</u> The volume of stock solution needed is 90 mL
<u>Explanation:</u>
To calculate the molarity of the diluted solution, we use the equation:

where,
are the molarity and volume of the stock sulfuric acid solution
are the molarity and volume of diluted sulfuric acid solution
We are given:

Putting values in above equation, we get:

Hence, the volume of stock solution needed is 90 mL
