How is molarity affected if some solution splashes out of the flask during titration?

Annette [7]

<span>If you used more water, the molarity would go down since molarity is moles/liter, and the opposite if you used more water.

If the acid absorbed water, the molarity would go down because the absorbed moisture will skew the weight of the acid up.

That would make the molarity go down since there would have been unreacted acid in the spilled liquid.</span>

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

What is the equilibrium constant expression for the given system?

artcher [175]

<h3>Answer:</h3>

$\displaystyle K_{eq} = \frac{[H_2]^2[O_2]}{[H_2O]^2}$

<h3>General Formulas and Concepts:</h3>

<u>Chemistry</u>

<u>Aqueous Solutions</u>

States of matter

<u>Kinetics</u>

Rate Laws

<u>Equilibrium</u>

Equilibrium Reactions RxN ⇄
Equilibrium Constants
Equilibrium Expression: $\displaystyle K = \frac{[Producst]^{coefficients}}{[Reactants]^{coefficients}}$

<h3>Explanation:</h3>

*Note: Only gases and liquids affect equilibrium

<u>Step 1: Define</u>

[RxN - Balanced] 2H₂O (g) ⇄ 2H₂ (g) + O₂ (g)

<u>Step 2: Identify</u>

[Reactant] H₂O

Coefficient of 2

[Product] H₂

Coefficient of 2

[Product] O₂

Coefficient of 1

<u>Step 3: Write K Expression</u>

Substitute: $\displaystyle K_{eq} = \frac{[H_2]^2[O_2]}{[H_2O]^2}$
