Answer to Question #146362 in General Chemistry for Bilal

Question

Q) For the following reaction, identify and the conjugate acid-base pairs

HF(aq)+OH-(aq)---> F-(aq) +H2O(I)

Q) A compound contains 46.7% silicon and 53.2% oxygen. What is the empirical formula of this compound?

Answer 1

Q1) HF is acid and OH- base because Whenever an acid donates a proton, the acid changes into a base, and whenever a base accepts a proton, an acid is formed. An acid and a base which differ only by the presence or absence of a proton are called a conjugate acid-base pair.

Q2) Si= 46.7%, O= 53.3 %.

46.7/28 : 53.3/16= 1,66785714 : 3,33125 | / 1,66785714 = 1:2.

SiO2.
