c) KOCl will be basic because KOH is a strong base while HOCl is a weak acid...Kb > Ka in this case The ammonium ion is a Bronsted-Lowery acid in that it will donate an H+ to solution. So yes, it is a weak acid (NH4+) and weak base (NO2-). Ka of HNO2 = 4.6 x 10-4. b: pH of the solution obtained on adding 20.0 ml of a 0.100 M HCl solution to 60.0 ml of a 0.100 M NaNO2 . H2SO4 and NaNO2 yield nitrous acid and sodium sulfate as, H2SO4 + 2NaNO2 ----->2HNO2 + Na2SO4 Is NaNO2 a base or an acid? Nitrogen dioxide is an acidic gas. Chemistry 112. As an ionic compound, it contains an anion. Essentially, a base accepts protons from acids. But you have to compare the Ka and Kb for these species before making a judgement! As a shortcut, you can remember that weak acids have strong conjugate bases, and strong acids have weak conjugate bases. It is the conjugate acid of a weak base (NH4+ is the conjugate acid of NH3) and the conjugate base of a weak acid (NO2- is the conjugate base of HNO2). And NH4NO3 is the salt of Strong acid and weak base so it is slightly acidic in nature. a) C5H5NHClO4 will be acidic because HClO4 is a strong acid while C5H5NH2 is a weak base....Ka > Kb in this case. Solutions for Acids and Bases Questions 2. Acid-base balance. Knowing that NaNO2 is the salt of a strong base and weak acid calculate... a: pH of 0.100 M NaNO2 solution. It is on the World Health Organization's List of Essential Medicines.. Food additive and preservative. NaNO 2 (aq) → Na + (aq) + NO 2 – (aq). Urine analysis. Nitrite is an easy way to give a pink shade to processed meats. Sodium nitrite is an efficient drug in case of cyanide poisoning.It is used together with sodium thiosulfate. d. Sodium hydrogen carbonate, NaHCO 3, is a weak base. If you want to quickly find the word you want to search, use Ctrl + F, then type the word you want to search. NO2 dissolves very well in water react with water to give nitrous acid and nitric acid. The only common strong base anion is hydroxide, so compounds containing the nitrite ion must be weak bases. HNO 2 (aq) + H 2 O(l) → ← H 3 O + (aq) + NO 2 – (aq). HF, as you recall, is a weak acid, so a little of it will want to dissociate back to F(-) and H(+), but the equilibrium is still mostly to the right, as you can see from the positive value for K. Therefore F(-) is a strong base. b) NH4NO2 ....both NH4OH and HNO2 are weak but HNO2's Ka is bigger than NH4OH Kb...so solution will be acidic. /Nitrate and nitrite poisoning/ Nitrogen dioxide is an acidic gas and produce an acidic solution with water (mixture of acids). When in solution, ammonium nitrate will dissociate very well into NH4+ and NO3-. c. Sulfuric acid, H 2 SO 4, is on the list of strong acids. Arterial blood gases. NaNO 2 - basic (NO 2-is a weak base - the conjugate base of a weak acid,HNO 2) NO 2-+ H2 O X HNO 2 + OH-NH 4 Cl - acidic (NH 4 + is a weak acid - the conjugate acid of a weak base, NH 3) NH 4 + + H 2 O X H 3 O + + NH 3 Li 2 SO 4 - basic (SO 4 2-is a weak base - the conjugate base of a weak acid,HSO 4 it is an acidic salt due to NH4+ ions being weak acid (pKa=9.2) NaNO2 is Base I'll tell you the Acid or Base list below. Toxicological analysis: The most relevant investigation is methemoglobin concentration which correlates well with symptoms and should be monitored according to the clinical condition.
