5. Conjugate Acids and Bases  A conjugate acid/base pair are two species that differ by a single proton.  A What % of the NH3 molecules have dissociated?  Since it is a weak base and the equilibrium is to the right we assume that at equilibrium, [NH3] is the same as stated in the question.The conjugate base of an acid is the substance that remains after the acid has donated its proton.Example: Acid is HX and conjugate base is X^-. Acid is HCl, conjugate base is Cl^Note that the validity of this assumption can be tested after calculation but for the purposes of exam questions in this chemistry course you can assume that the assumption is always valid. Therefore pKB of CH3CH2NH2 (the conjugate base of CH3CH2NH3+).This calculator extracts the square root, calculate the modulus, finds inverse, finds conjugate and transform complex number to polar form. The absolute value of the complex number z = a + bi isB) What is pKb of the conjugate base of X-281? Home» Questions »Science/Math » Chemistry » Chemistry - Others » To find the pKa of X-281, you prepare a 0.084 M...

What is the conjugate base for HPO22? - Answers

As a research technician at Pharma-pill, you are told that X-281 is a monoprotic weak acid, but because of security concerns, the actual chemical formula The company is interested in the drug's K_a value because only the dissociated form of the chemical is active in preventing cholesterol buildup in arteries.When we make a measurement, we generally assume that some exact or true value exists based on how we define what is being measured. While we may never know this true value exactly, we attempt to find this ideal quantity to the best of our ability with the time and resources available.2. The conjugate base of a weak acid is a weak base (the weaker the acid, the stronger the conjugate base). B. Kw = [H3O+][OH-] = 1.0 x 10-14 (this is at 25° C; Kw ↑ with ↑ T). (i) Since Ka is so small, that means hardly any HCN dissociates, and we can assume that (0.2-x) is essentially the...The conjugate base of HPO42− is. A. PO43−. CH3 COO(aq) Ka =1.8×10−5 Which is the strongest acid and which acid has the strongest coniugate base?

Acids and Bases (2)

Strong and weak acids and bases. Neutralization Reactions. Acid and base Dissociation Constant: Ka and Kb. E) НОАс and HCHO2. Using the data table, which of the conjugate acids is the weakest acid?? 15) The Ka of hypochlorous acid (HCIO) is 3.0 x 10" at 25.0°C. What is the % ionization of...Simply remove #H^+# from your base from your base formula; conserve mass and charge. The conjugate base of dihydrogen phosphate is #HPO_4^(2-)# (so you know the conjugate acid, why?).(assume x << 5.0). NOTE: (i) pKb = -log Kb (ii) just like pKa, strength of base increases with decreasing pKb (See Table 18.6). C. Basic Solutions (Only one way.) The anion (i.e., the conjugate base) of a weak acid (F-, NO2-, ClO-, acetate-, PO43-, etc.) and the cation of a strong base (Na+, K+...conjugate base : substance formed when an acid loses a hydrogen ion . Considered a base because it can gain a hydrogen ion to reform the acid . What is a conjugate base? Ad by Blissy.Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution, and you may not use the same element twice. You can return the answer in any order.

Just goes to show how lost I am haha sorry

details:

A new potential heart medicine, code-named X-281, is being tested by a pharmaceutical company, Pharma-pill. As a research technician at Pharma-pill, you are told that X-281 is a monoprotic weak acid, but because of security concerns, the actual chemical formula must remain top secret. The company is interested in the drug's K_a value because only the dissociated form of the chemical is active in preventing cholesterol buildup in arteries.

To find the {\rm p}K_{\rm a} of X-281, you prepare a 0.086\it M test solution of X-281. The pH of the solution is determined to be 3.00. What is the {\rm p}K_{\rm a} of X-281?

4.93 = pka
