In the titration of wine to determine the acid concentration, 10.0 mL of wine was placed in a beaker and diluted with 40.0 mL of

BARSIC [14]

Answer:

0.0042 M is the molarity of tartaric acid in this sample of wine.

Explanation:

To calculate the concentration of acid, we use the equation given by neutralization reaction:

$n_1M_1V_1=n_2M_2V_2$

where,

$n_1,M_1\text{ and }V_1$ are the n-factor, molarity and volume of acid which is tartaric acid

$n_2,M_2\text{ and }V_2$ are the n-factor, molarity and volume of base which is NaOH.

We are given:

$n_1=2\\M_1=?\\V_1=10.0+40.0 mL=50.0 mL\\n_2=1\\M_2=0.051 M M\\V_2=8.20 mL$

Putting values in above equation, we get:

$2\times M_1\times 50.0 mL=1\times 0.051 M\times 8.20 mL$

$M_1=\frac{1\times 0.051 M\times 8.20 mL}{2\times 50.0 mL}=0.0042 M$

0.0042 M is the molarity of tartaric acid in this sample of wine.

What leads to the formation of an ionic bond with Hg2+?

statuscvo [17]

The attraction of an $SO_4^{2-}$ ion leads to the formation of an ionic bond with $Hg^{2+}$

<h3>What is an ionic bond?</h3>

Ionic bond, also called an electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound.

Since the question asking among all these options:

(a) The attraction of a noble gas

(b) The attraction of a $NH^{4+}$ ion

(d) The attraction of a $SO_4^{2-}$ ion

An ionic bond can be formed after two or more atoms lose or gain electrons to form an ion. Ionic bonds occur between metals, losing electrons, and nonmetals, gaining electrons.

Hence, option D is correct.
