Answer:
CH3COONa : CH3COOH = 1.74 : 1 (required to prepare a buffer at PH = 5)
Explanation:
Given that :
PH = 5
Calculate proportions of ethanoic acid and Sodium ethanoate to prepare Buffer solution
solution :
PH = Pka + Log ( CH3COONa / CH3COOH )
5.0 = 4.76 + Log ( CH3COONa / CH3COOH )
∴ Log ( CH3COONa / CH3COOH ) = 0.24
( CH3COONa / CH3COOH ) = 1.74
Therefore : CH3COONa : CH3COOH
1.74 : 1
As - 8 dots and 3- charge, Se - 8 dots and 2- charge, Br - 8 dots and 1-, K - zero dots and +1 charge, Ca - zero dots and +2 charge, Ga - zero dots and +3 charge.
<h3>In the periodic table of the elements, what is its Lewis symbol?</h3>
The valence electrons of each element are represented by dots that surround their chemical symbol in a Lewis dot symbol. The Lewis dot symbol's dots correspond to the valence electrons, which correspond to the final digit of the element's group number as in periodic table.
<h3>What's an example of a Lewis symbol?</h3>
Two chlorine atoms, for instance, share one pair of electrons when they combine to form a chlorine molecule. According to the Lewis structure, each Cl atom contains one shared pair of electrons and pairs of electrons that aren't employed in bonds (known as lone pairs) (written between the atoms).
