Idk really know how to solve that sorry I'm only in high school
pH of mixed solution = 4.3
<h3>Further explanation
</h3>
A buffer solution is a solution that can maintain a good pH value due to the addition of a little acid or a little base or dilution.
The buffer solution can be acidic or basic
Acid buffer solution consists of weak acids and their salts.
valence according to the amount of salt anion
mol CH₃COOH = 25 ml x 0.9 = 22.5 mlmol
mol NaOH = 25 ml x 0.45 = 11.25 mlmol
ICE method :
Reaction
NaOH + CH₃COOH ---> CH₃COONa + H₂O
11.25 22.5
11.25 11.25 11.25 11.25
11.25 11.25 11.25
mol acid = 11.25, mol salt = 11.25, Ka CH₃COOH = 5.10⁻⁵
Then [H⁺]=
Answer:
Add water to 29.22 grams of salt until you get 1 liter of volume, stir it until the salt completely dissolves and mixes and voila! you will have a 0.5 M NaCl solution.
:)
The answer is perpendicular.
Hope that helped u;) ⭐
The name for NH3 is Nitrogen trihydride.
