Strong versus weak acids what makes a strong acid strong pogil answer key

An acid is deemed strong if it can readily or easy "donate" a proton (H+) to the other ions in the solutions. Also, to donate or lose the proton or H+, the acid must dissociate (split into ions) in the solution. The more it can readily dissociate, the stronger the acid is.

<h2>Strong Versus Weak Acids </h2>

Strong acid is the acid that can absolutely dissociated in aqueous solution and weak acids are unlike the strong acids which cannot be dissociated or ionized in aqueous solution completely. Their dissociation power makes the acid strong or weak. If they dissociate completely then they will be strong and vice versa. Hydrochloric acid(HCl), H2SO4,etc are the strong acids and acetic acid(CH3COOH), lactic acid, etc are weak acids.

Following the instructions in your lab manual, you have titrated a 25.00 mL sample of 0.0100 M KIO3 with a solution of Na2S2O3 o

vivado [14]

<u>Answer:</u>

<u>For 1:</u> The amount of potassium iodate that were titrated is $2.5\times 10^{-4}$ moles

<u>For 2:</u> The amount of sodium thiosulfate required is $1.25\times 10^{-4}$ moles

<u>Explanation:</u>

<u>For 1:</u>

To calculate the number of moles for given molarity, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in L)}}$

Molarity of $KIO_3$ solution = 0.0100 M

Volume of solution = 25 mL

Putting values in above equation, we get:

$0.0100M=\frac{\text{Moles of }KIO_3\times 1000}{25}\\\\\text{Moles of }KIO_3=\frac{0.0100\times 25}{1000}=0.00025mol$

Hence, the amount of potassium iodate that were titrated is $2.5\times 10^{-4}$ moles

<u>For 2:</u>

The chemical equation for the reaction of potassium iodate and sodium thiosulfate follows:

$2KIO_3+Na_2S_2O_3\rightarrow K_2S_2O_3+2NaIO_3$

By Stoichiometry of the reaction:

2 moles of potassium iodate reacts with 1 mole of sodium thiosulfate

So, 0.00025 moles of potassium iodate will react with = $\frac{1}{2}\times 0.00025=0.000125mol$ of sodium thiosulfate

Hence, the amount of sodium thiosulfate required is $1.25\times 10^{-4}$ moles
