Calculate the ph of a 0.10 m solution of hypochlorous acid

Chemistry
1 answer:
melomori [17]2 years ago
8 0

Answer:

1

Explanation:

Firstly we need to know the chemical formula of hypochlorous acid. This is HOCl.

The ionization equation is as follows:

HOCl ⇌ ClO− + H

This means in every one mole of the acid, exactly one mole of hydrogen ions is produced. This also means that there is exactly 0.1M of H+ in 0.1M of the acid.

We now go on to calculate the pH of the acid solution. By definition, the pH is the negative logarithm to base 10 of the hydrogen ion concentration of the acid.

Mathematically: pH = -log[H+]

Now we know that [H+] = 0.1M

pH = -log[0.1]

pH = 1

The pH of 0.1M hypochlorous acid is 1

Svetradugi [14.3K]

Answer:

2-chloro-4-methylpentanal.

Explanation:

Hello there!

In this case, according to the chemical compound:

CH3-CH-CH2-CH-CHO

          |              |

        CH3        Cl

We can see the main functional group is an starting carbonyl, which means this is an aldehyde. Moreover, we can see a Cl-substituent on the second carbon and a methyl substituent on the fourth carbon. Therefore, the IUPAC name turns out: 2-chloro-4-methylpentanal.

Best regards!

How many atoms are in 3 moles of nitrogen
olga nikolaevna [1]

Answer:1 mol of Mg(NO3)2 contains 6.022*10^23 molecules

3 mol Mg(NO3)2 contains 3*6.022*10^23 = 1.81*10^24 molecules

Each Mg(NO3)2 molecule contains 2 N atoms  

Number of N atoms = 2*1.81*10^24 = 3.62*10^24 N atoms.
