Answer:
d) Make it flexible
Step-by-step explanation:
Raw hides dry out to form a hard material that can decay with an offensive smell when they become wet.
Tanning converts the protein of the raw hide into a stable material that will stay flexible and not decompose when it gets wet.
a) is <em>wrong</em>. The purpose of tanning is to soften the leather.
b) is <em>wrong</em>. You smooth the leather manually with fine sandpaper.
c) is <em>wrong</em>. Tanning does not impart water resistance. It prevents the leather from putrefying when it does get wet.

Answer: <span>The coordination number of the central metal ion in [Co(C</span>₂<span>O</span>₄<span>)2(OH)</span>₂<span>]</span>⁻³ <span> is
6.
Explanation: Coordination number is defined as the number of neutral atoms or ions surrounding the central metal atom.
In given case there are four ligands surrounding the Co central atom.
1) Oxalate Ion: Oxalate ion has two negative charges (shown below). So each oxalate makes two coordinate covalent bonds with central metal atom and four coordinate covalent bond by two Oxalate Ions.
2) Hydroxyl Ion: Hydroxyl ion has one negative charge. Hence it makes one coordinate covalent bond with Co atom.</span>
