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 charge by one. Vocabulary and Equations for Determining the Conjugate Acid or Base Bronsted-Lowry Acids and Bases: Wh...
It is important to note, as the strength of an acid increases, the strength of its conjugate base decreases. As the strength of an acid decreases, the strength of its conjugate base increases. Vice versa, if a strong base is present in a chemical reaction, its conjugate acid will be weak...
Is H2SO4 an acid or a base? How do you know? How do you determine the formula for the conjugate base of an acid? Identify the acid and the base in the following reaction: HF(aq) + OH-(aq) F-(aq) + H2O(l). How would you test a solution to find out if it is acidic or ...
Calculate the pH of a buffer that contains the following acid and conjugate base concentration of: HNO_2 = 0.029; NO_2^- = 0.065 The pKa of HNO_2 = 3.33. What is the pH of an aqueous solution of acetic acid (pKa = 4.76) if the ratio of conjugate base to conj...
How do you know if its acid or base? To determine whether a substance is an acid or a base,count the hydrogens on each substance before and after the reaction. If the number of hydrogens has decreased that substance is the acid (donates hydrogen ions). If the number of hydrogens has...
A high value of pKa (e.g. 50) indicates a weak acid. Acid base reactions have four components: an acid and a base exchange a bond to H to give a conjugate acid and a conjugate base. Acid-base reactions can always be written as equilibria; that is, occurring in a forward or a ...
Start with the Henderson-Hasselbach equation, use it to find ratio of acid and conjugate base. You know sum of their concetrations - 10 mM. That gives you two equations in two unknowns, solve and you know concentrations of both acid and conjugate base. Then it is just a matter of ...
Swiss chocolatier Daniel Peter first had the idea of adding milk to chocolate to mellow out its flavor, before forming the Nestlé Company with Henri Nestlé. Contemporary, smooth milk chocolate as we know it was then produced a few years later by Rodolphe Lindt, and the modern chocolate indust...
The intestinal flora composed of Bifidobacterium and Lactobacillus plays a non-specific immune function by occupying space and producing bacteriocin, organic acid, hydrogen peroxide and other substances. Intestinal flora can also be used as antigen to stimulate and promote the development and maturation ...
Related to this Question Is the conjugate base of a weak acid a strong base? Explain. Explain the following statement: "A strong acid has a weak conjugate base, whereas a weak acid has a relatively strong conjugate base." Please answer and explain: Which...
