Answer:
An aqueous solution of 
will be an acid and have a pH of less than 7.
An aqueous solution of 
will be a neutral solution and have a pH equal to 7.
An aqueous solution of 
will be an base and have a pH of more than 7.
Explanation:
pH is defined as the negative logarithm of the concentration of hydrogen ions.
Thus,
pH = - log [H⁺]
pH scale generally runs from 1 to 14 where pH = 7 represents neutral medium, pH < 7 represents acidic medium and pH > 7 represents basic medium.
Thus,
<u>An aqueous solution of will be an acid and have a pH of less than 7.</u>
<u>An aqueous solution of will be a neutral solution and have a pH equal to 7.</u>
<u>An aqueous solution of will be an base and have a pH of more than 7.</u>
0.0788 will be the number of moles of silver in coin.
<h3><u>How to find the number of moles?</u></h3>
A mole is the mass of a material made up of the same number of fundamental components. Atoms in a 12 gram example are identical to 12C. Depending on the material, the fundamental units may be molecules, atoms, or formula units.
A mole fraction shows how many chemical elements are present. The value of 6.023 x 10²³ is equivalent to one mole of any material (Avagadro's number). It can be used to quantify the chemical reaction's byproducts. The symbol for the unit is mol.
The number of moles formula is denoted by the following expression:
Number of moles = Mass of substance/mass of one mole
