Atitration was performed in a lab situation. h2so4 was titrated with naoh. the following data was collected: ml of naoh used = 43.2 ml concentration naoh = 0.15 m ml h2so4 = 20.5 ml notice that h2so4 releases 2 h+ per mole. what is the concentration of h2so4? 0.036 m 0.16 m 0.63 m 6.3 m

The concentration of comes out to be 0.16 M.

Explanation:

To calculate the concentration of acid, we use the equation given by neutralization reaction:

where,

are the n-factor, molarity and volume of acid which is

are the n-factor, molarity and volume of base which is NaOH.

We are given:

Putting values in above equation, we get:

Hence, the concentration of comes out to be 0.16 M.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
