Answer:

Volume of acid Va = 38.70cm3,

Concentration of acid Ca = 1.90M

Volume of Base Vb = 10.30cm3

Concentration of base Cb = ?

Equation of the reaction

H2SO4 + 2NaOH = Na2SO4 + 2H2O

No of mole of acid Na = 1

No of mole of base Nb = 2

CaVa/CbVb = Na/Nb

Cb = CaVaNb/VbNa

Cb = 1.9*38.7*2/10.30*1

Cb = 14.2777M

If a substance undergoes electrolysis and a brown solid forms on one electrode and a gas on the other, from this we can conclude
andrew-mc [135]

Answer:

b. a compound.

Explanation:

Electrolysis is described as a mechanism in which ionic compounds are decomposed into their elements by transmitting a direct electric current via the compound in a liquid state. At the cathode, the cations are reduced and anions at the anode are oxidized. There is an exchange between ions and atoms in the electrolysis process caused by the addition or removal between electrons from the external circuit. As per the question, the original substance is a compound because the electrolysis method is used to obtain pure elements from their respective compound.
