As you saw in the video, the ph of a 0.1 m solution of acetic acid, hc2h3o2, (ka ≡ 1.8 × 10−5) is 2.9. based on this observation, which statement below best describes the ph of a 0.1 m solution of lactic acid, hc3h5o3, (ka ≡ 1.4 × 10−4)? view available hint(s) as you saw in the video, the ph of a solution of acetic acid, , () is . based on this observation, which statement below best describes the ph of a solution of lactic acid, , since lactic acid has a smaller acid dissociation constant than acetic acid, a 0.1 m solution of lactic acid will have a larger ph value than a 0.1 m acetic acid solution. the ph of a 0.1 m acetic acid solution will be equal to the ph of a 0.1 m lactic acid solution since both are weak acids. since lactic acid has a larger acid dissociation constant than acetic acid, a 0.1 m solution of lactic acid will have a smaller ph value than a 0.1 m acetic acid solution. since lactic acid has a larger acid dissociation constant than acetic acid, a 0.1 m solution of lactic acid will have a larger ph value than a 0.1 macetic acid solution.

Molarity of solution = 0.08 M

Further explanation  

Molarity shows the number of moles of solute in every 1 liter of solution or mmol in each ml of solution  

 

Where  

M = Molarity  

n = number of moles of solute  

V = Volume of solution  

mol of NaOH

molarity

Volume of solution = 100 ml + 150 ml = 250 ml
