Birds
Explanation:
Some types of birds eat seeds do they use there beaks to easily crack through the seeds
- A buffer solution resists the change in pH after the addition of small amounts of acid or base to it.
- The given buffer solution is NaHCO₃ (acid) + Na₂CO₃ (conjugate base).
- NaHCO₃ contains HCO₃⁻ and Na⁺ ions. Na₂CO₃ contains Na⁺ and CO₃²⁻ ions. Na⁺ ions do not show any effect on the pH of a solution.
Therefore, HCO₃⁻ and CO₃²⁻ are responsible for the buffer action.
HCO₃⁻ is the acidic component of the buffer. It neutralizes the small amounts of base added to it producing an equivalent amount of the conjugate base CO₃²⁻.
HCO₃⁻(aq) + OH⁻(aq) → CO₃²⁻(aq) + H₂O(l)
Acid conjugate base
CO₃²⁻ is the basic component if the buffer. It neutralizes the small amounts of acid added to it producing an equivalent amount of the conjugate acid HCO₃⁻
CO₃²⁻(aq) + H₃O⁺(aq) → HCO₃⁻(aq) + H₂O(l)
Base Conjugate acid
- Therefore, even after the addition of a small amount of acid or base to the buffer, pH remains unchanged.
A monobromination reaction of an alkane involves an alkane and bromine. The position of the hydrogen atom that will be substituted by the bromine free radical will depend on the order of the alkane. The bromine will attach to the carbon that has the most substituents.
