Steps to Find the Conjugate of an Acid Step 1: Remove a hydrogen atom from the acid given. Step 2: Add a unit of negative charge to the molecule. Vocabulary for Finding the Conjugate of an Acid Acid: A molecule that donates or loses a proton. Proton: A subatomic particle with a...
Write the formula of the conjugate base for each of these Bronsted-Lowry acids. HBr H2CO3 CH3NH+ HSO4− Step 1: If asked for the conjugate acid, attach an H to the given formula and increase its charge by one. If asked for the conjugate base, remove an H and decrease its...
Explain the terms "strong acid" and "concentrated acid." Are these terms interchangeable? What is the difference among the following: strong acid, weak acid, polyprotic acid? What does base strength and acid strength mean? What is strong about a strong acid. What is common to all acids?
Lewis Structures: Lewis structures are pictoral diagrams of molecules used to demonstrate the arrangement of covalent bonds between atoms. They are determined by trying to satisfy the octet of each atom whilst ensuring that the total number of valence electrons in the molecule overall stays constant....

You can write an undissociated acid schematically as HA, or you can write its constituents in solution as H+ (the proton) and A- (the conjugate of the acid). For example, formic acid (found in ant venom) is HCOOH, but its components are H+ and COOH-. Importantly, when this comparat...
Now we're ready to tackle part (a): Where's the conjugate acid-base pair in the equation? There are two pairs that you could potentially list for this answer: CH3CH2COOH (acid) and CH3CH2COO-(base) OR H30+(acid) and H20 (base) ...
22.Your teacher will assign you the pH of a buffer to prepare. Calculate the volume of weak acid and conjugate base that you will need to prepare 50 mL of a buffer of the assigned pH. 23.Measure out the volumes of acid and conjugate base, mix then measure and record the pH. ...
What is the quickest way to find out whether a compound is acidic or basic? What is a more accurate (quantitative) way of finding out whether a compound is acidic or basic? Is H2S an acid or a base? Identify its conjugate acid or base. Is HS- an acid or a base? Identify its con...
A buffer is a substance that maintains the pH of a solution. Generally, a buffer contains a conjugate acid/base pair of a weak acid and weak base. If an acid is added to the solution, it will react with the weak base and the pH of the solution will change very ...
