Which of these conjugate acid-base pairs will not function as a buffer?A) HNO3 and NO3^-B) HCO3^- and CO3^2-C) C2H5COOH and C2H5
marin [14]
<h3><u>Answer;</u></h3>

A) HNO3 and NO3^-

<h3><u>Explanation;</u></h3>
  • <em><u>HNO3 is a strong  acid and NO3 is its conjugate base, meaning it will not have any tendency to withdraw H+ from solution.</u></em>
  • Buffers are often prepared by mixing a weak acid or base with a salt of that weak acid or base.
  • The buffers resist changes in pH since they contain acids to neutralize OH- and a base to neutralize H+. Acid and base can not consume each other in neutralization reaction.

Which of the answer choices correctly describes a solvent made of molecules that have areas of partial positive and negative cha
damaskus [11]

Answer: polar solvent

Explanation:

Polarity can be said to mean, charge separation. Thus, polar solvents are solvents that have charge separation and the ability to solvate i.e dissolve ions.

A polar solvent molecule has slight electrical charge as a result of its shape. A typical and most common example is water, with an oxygen and two hydrogen atoms. The two hydrogen atoms are at an angle to the single oxygen atom. Water is the classic polar solvent. The oxygen atom tends to polarize electron density to itself.
