Chemistry

disa [49]4 years ago

The equilibrium constant expression for this reaction that takes place in water and involve ions can be written as K=  [H_3 O^+ ][OH^- ]/([H_2 O]  ^2 ). But the concentration of undissociated water, H_2 O is much larger than the concentration of the ions that is essentially remains constant. Therefore, we can include it in the equilibrium constant. The resulting new equilibrium constant can be written:  K_W= [H_3 O^+ ][OH^- ].

A 28. 0 ml sample of vinegar, which is an aqueous solution of acetic acid, ch3cooh, requires 21. 5 ml of 0. 550 m naoh to reach
Fittoniya [83]

Concentration of vinegar sample of 28mL which requires 21. 5 ml of 0.550 M NaOH to reach the endpoint in a titration is 0.42M.

<h3>How do we calculate the concentration of Vinegar?</h3>

Concentration of vinegar in the titration method will be used by using the below equation:

M₁V₁ = M₂V₂,

  • M₁ & V₁ are the molarity and volume of acetic acid.
  • M₂ & V₂ are the molarity and volume of vinegar sample.

By putting values on above equation from the question, we get

M₂ = (0.55M)(21.5mL) / (28mL) = 0.42 M

Hence, required concentration of vinegar is 0.42M.

What is the pOH of a 1 x 10^-8 M solution of HNO3?
Sedaia [141]

Explanation:

to find POH u need PH first

so ph=-log(h3o)

so

ph =  -  log(1 \times  {10}^{ - 8} )  \\  \\ ph = 8 \\ ph + poh =14 \\ poh = 14 - 8 \\ poh = 6
