Fatima adds 0.1 moles of hcl to a buffer mixture containing 1.0 mole of naf and 1.0 mole of hf in 1.0 l of water at 298 k. which component of the buffer mixture does the hcl react with?

HCl reacts with NaF

Explanation:

A buffer is defined as the mixture of a weak acid (HX) with its conjugate base (X⁻) or vice versa.

The buffer in the problem is the mixture of HF -weak acid- with NaF -conjugate base, F⁻-. A strong acid as HCl reacts with the conjugate base,  F⁻, producing weak acid, HF. The reaction is:

HCl + F⁻ → HF + Cl⁻

Thus, HCl reacts with NaF.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer
