Answer: a.KOH

Potassium hydroxide is an ionic compound where the K+ is the cation and OH−is the anion. At the same time, the compound also contains a covalent bond since the anion, OH−is formed from electron sharing between the O and H atoms.

Hope this helps........ Stay safe and have a Merry Christmas! :D

The ionization constant equation is:

K_{w}=1.0 × 10^{-14} at 25°C

the option is 1.

Explanation:

Sometimes in pure water one proton of the water molecule(hydrogen ion) will get attracted to the lone pairs present in another water molecule.This causes the hydrogen ion to leave the present water(leaving the OH^{-} behind) molecule ad gets attached to another water molecule leading  to the formation of the hydronium ion(H^{3} O{+},hydronium ion).

This process is called auto-ionization of water because the water molecule ionizes into H^{+} and OH^{-} ions.

<h2>H_{2}O<u>+</u>H_{2} O<u>→</u>H^{3} O{+}<u> + </u>OH^{-}</h2>

As such the equilibrium constant,which is measure of concentration of products to concentration of reactants,will be very slow.

∴the ionization constant of water at 25°C is 1.0 × 10^{-14}.

(i.e.)option<u> c</u> is correct answer [H^{+}]=[OH^{-}]

A student measured the volume of water to be 18.5 ml; the actual volume was 17.5 ml. What was the % deviation
Step2247 [10]

Answer:

+5.7%

Explanation:

18.5mL/17.5mL = 1.057 = 105.7% - 100% = 5.7%

Since the measured volume was higher, it is PLUS 5.7%
