Scientists will often use a(n) _________________, an object that helps explain ideas about the natural world.
The answer is model.
The unbalanced Equation is
electricity
KI (aq) + H2O (l) -------------> H2 (g) + I2(g) + KOH(aq)
<u>Answer:</u> The concentration of 
comes out to be 0.109 M.
<u>Explanation:</u>
To calculate the concentration of acid, we use the equation given y 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 KOH.
We are given:
Putting values in above equation, we get:
Hence, the concentration of comes out to be 0.109 M
