According to the conjugate acid-base pair, the nature of the compound and its corresponding pair is always opposite in nature. A strong acid always forms a weak conjugate base. A strong base always forms a weak conjugate acid. A weak acid always forms a strong conjugate base. A weak base ...
What is [Al(H2 O)5(OH)2+] in a 0.15-M solution of Al(NO3)3 that contains enough of the strong acid HNO3 to bring [H3O+] to 0.10 M? What is the (OH^-) of a 0.00756 M HNO_3 solution? What are the two step...
Engineering. Consider the example of HNO2 reacting with H2O. Is HNO2 strong or weak? [Quick overview], Is SiCl2F2 Polar or Nonpolar? On the flip side, a 0.0005 M HCl solution is dilute, yet still strong. Conjugate acid is an acid that formed when the parent base compound gains one p...
Answer to: Which of the following is a strong acid/base? i. A solution with pK_a = 4.74 or pK_a = 2.5. ii. A solution with K_b = 1.8 times 10^{-5}...
a) H2O, O b) H3O+, OH- c)H2CO3, CO3^{2} d) HCI, CI e) H2CO3, HCO3- Which of the following is not a conjugate acid base pair? a. H_3O^+/OH^- b. NH_4^+/NH_3 c. C_2H_3O_2^-/HC_2H_3O_2 d. H_2...
What is the conjugate base of HClO4? Which is the conjugate acid of HPO42-? a. H3O+ b. H2PO4- c. H3PO4 d. PO43- What is the formula for the conjugate base of HBr? What is the conjugate base of NH3? What is the conjugate base of NH_3?
because it is a weak acid. Equalibrium. As ethanoic acid added into water it immediately dissociates/ionizes to produce H3O+ ions and that's why the solution changes from pH of 7 to < 7. Due to the nature of Weak acid therefore it is a strong conjugate base (CH3COO-) ...
or donate electrons (Lewis definition) :H Cl + H O H H O H H ClIn this case HCl is the acid (proton donor), water is the base (electron donor, proton acceptor) and the arrows show the proton being transferred to generate the conjugate acid (H3O+) and the conjugate base (Cl-). ...
(HC2H3O2) = 1.8 x 10 -5 so pKa = -log10Ka = 4.74. Thus when [HC2H3O2] = [C2H3O2 – ], pH = pKa = 4.74. 1 2 Basic Buffers In a basic buffer both the weak base and conjugate acid are present initially in roughly equal concentrations. The equilibrium is B + H2O BH + + OH...
Acid and base are two behavior of a chemical. Except for acid and base, a chemical can be found in the neutral behavior as well. These behaviors of a chemical are different according to the concentration of hydrogen ion or hydroxide on it or its pH value. The term alkalinity...
