If you dissolve 0.1 mol of formic acid in 1 L of water, ther esulting solution contains 0.004 mol of H₃O+. Based on this informa
zhuklara [117]

In an ideal case, the acid would completely protonate. such an acid would be a strong acid.  Dissociation of Formic acid looks like:

HCOOH + H₂O → COOH⁻ + H₃O⁺

one mole of formic acid should give one mole of Hydronium(H₃O⁺) ions

similarly, 0.1 moles of formic acid should produce 0.1 moles of hydronium ions. but we know that it is not the case, a much lesser amount is actually formed.

Which means that Formic acid did not completely dissociate into COOH⁻ and H⁺ ions.

Hence, Formic Acid is a weak acid

You add 168.90 grams of NaCl to a container and then you add 616.00 grams of water to that same container What is the weight per
erma4kov [3.2K]

Answer:

The weight percent of NaCl in the container​ is 21.5%

Explanation:

Given that,

Mass of NaCl = 168.90 gram

Mass of water = 616.00 grams

We need to calculate the weight percent of NaCl in the container​

Using formula of percentage of weight

weight\ \%\  of\ component\ of\ the\ solution =\dfrac{weight\ of\ the\ component\ in\ the\ solution}{total\ weight\ of\ the\ solution}\times100

Put the value into the formula

weight\ \%\  of\ component\ of\ the\ solution =\dfrac{168.90}{168.90+616.00}\times100

weight\ \%\  of\ component\ of\ the\ solution=21.5\%

Hence, The weight percent of NaCl in the container​ is 21.5%
