a weak base is added to water. which information is required to find the strength of its conjugate acid?\no the value of $k_b$ and the concentration of the weak base\no the value of $k_w$ only\no the values of $k_b$ and $k_w$\no the values of and $k_w$ and the concentration of the weak base
Answer
Brief Explanations:
The relationship between the base - dissociation constant ($K_b$) of a weak base, the acid - dissociation constant ($K_a$) of its conjugate acid, and the ion - product constant of water ($K_w$) is given by $K_w=K_a\times K_b$. To find the strength (represented by $K_a$) of the conjugate acid of a weak base, we need to know the value of $K_b$ of the weak base and $K_w$ (which is a constant at a given temperature, $K_w = 1.0\times10^{- 14}$ at $25^{\circ}C$). The concentration of the weak base is not required to find the value of $K_a$ of its conjugate acid.
Answer:
the values of $K_b$ and $K_w$
