Which of the following ions is formed when a base is dissolved in a solution?

Chemistry
1 answer:
Aneli [31]2 years ago
3 0

Answer:

\huge\boxed{\sf OH-}

Explanation:

<u>According to Arrhenius concept of acid and base:</u>

"When a base in a solution, produces/yields OH- (Hydroxide) ions."

So, when a base is dissolved in a solution, it produces OH- ions.

<u>For example:</u>

NaOH ⇄ Na⁺ + OH⁻ (So, it is a base)

\rule[225]{225}{2}

Hope this helped!

Looking at this equation P= (pa*pb)/ (pa+(pb-pa)) ya  where pa=vap press a and ya= vap composition a and P= total pressure,it relates vapor pressure mixture to vapor composition. This is derived using the combination of Dalton's and Raoult's laws.

The gas arsine, AsH3, decomposes as follows: In an experiment at a certain temperature, pure AsH3(g) was placed in an empty, rig
bazaltina [42]

The equilibrium pressure of H_{2} is 288 torr. and K_{p} for this reaction is 0.786 atm.

from the reaction:-        2AsH_{3} ⇄ 2As + 3H_{2}

initial concentration     392 torr.              0

at equilibrium.              392 - 2x.               3x

and the final pressure in the flask = 488 torr.

Hence,

( 392 - 2x ) + 3x = 488\\ x = 488-392\\x = 96 torr.

The partial  pressure of H_{2} is 3 × 96 =  288 torr.

and AsH_{3} is 392 - ( 2 × 96 ) = 392 - 192 = 200 torr.

Now, to find K_{p} for this reaction, we will use K_{p} = \frac{(P_{H_{2} })^{2}  }{( P_{AsH_{3} } )^{2}}

putting all the values, we get,

K_{p} = \frac{(288)^{3} }{(200)^{2} }

     = 597.1968 torr.

     = 0.786 atm.  ( 1 atm = 760 torr. )

what do you mean by equilibrium?

Equilibrium in chemistry is the phase that exists when a chemical reaction and its opposite reaction happen at the same rates. This word's Latin origin dates back to the prefix aequi-, which means equal, and lbra, that indicates scale or balance.

In which type of chemical bonding are electrons shared between adjacent atoms?
Vikki [24]
In covalent bonding electrons are shared betweed adjacent atoms.

This kind of bonding means that none of the atoms are detached from its electrons.

A molecule of compound is formed when two or more atoms are bonded through covalent bonds. The electrons shared are considered part of the valence electrons (outer energy level) of both atoms forming the covalent bonding.
