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>
That’s nice. Maybe bring your own next time
Answer:
A) high spin complex
B) low spin complex
Explanation:
A) VCI3(H20)3 is a high spin complex and this is because the complex has a weak field ligands all . this weak field ligands makes it impossible for pairing to take place
B) Fe(NH3)23 is a low spin complex and this is because the complex is made up of strong field ligands, this strong field ligands makes it possible for paring to take place
note : Ligands in which its donor atoms are ; Nitrogen,phosphorous or carbon are considered strong ligands
