What do acids and bases have in common apex?
2 answers:
Explanation:
Acids are the substances that have pH less than 7. They are acidic in nature and have a sour taste.
Acids give hydrogen ions () upon dissociation in water.
On the other hand, bases are the substances that have pH more than 7. They are basic in nature and have bitter taste.
Bases dissociate in water to give hydroxide ions ().
Since, both acids and bases dissociate to give ions. Hence, we can conclude that both acids and bases are able to conduct electricity.

Answer: Theoretical Yield = 0.2952 g
Percentage Yield = 75.3%
Explanation:
Calculation of limiting reactant:
n-trans-cinnamic acid moles = (142mg/1000) / 148.16 = 9.584*10⁻⁴ mol
pyridium tribromide moles = (412mg/1000) / 319.82= 1.288*10⁻³ mol
- n-trans-cinnamic acid is the limiting reactant
The molar ratio according to the equation mentioned is equals to 1:1
The brominated product moles is also = 9.584*10⁻⁴ mol
Theoretical yield = (9.584*10⁻⁴ mol) * (Mr of brominated product)
= (9.584*10⁻⁴ mol) * (307.97) = 0.2952 g
Percentage Yield is : Actual Yield / Theoretical Yield = 0.2223/0.2952
= 75.3%
