2018年4月16日 · When the titration occurrs you have used 25,0 mL of NaOH so you in total have 50.0 mL of #NaNO_2# that (because the volume is double) will be 0.075 M

2017年5月12日 · Generally, we consider strong acids to dissociate more in water than hydronium ions do. Since the "pKa" of hydronium is about -1.7, we consider strong acids to have "pKa"s …

2014年12月28日 · Bronsted defines an acid is a proton (H+) donor, and a base is an H+ acceptor. Lewis defines an acid as an electron (e-) acceptor and base as an e- donor.

2015年7月31日 · "H"_2"SeO"_4 is the stronger acid. > For oxyacids with the same central atom, the acidity increases as the number of atoms bonded to the central atom increases. Thus, we …

2016年1月26日 · HCl ,CH3COOH, HNO2,NH3,KOH, pyridine. Write as many salts formula. For each salt,write chemical equation when salt dissolved in water.

2014年7月17日 · Whichever one produces the least is going to be the limiting reactant. You may use the mole ratio (coefficients in balanced equation) to do this. Example: (1.01966 mol …

On reaction with nitrous acid, the ethanamine can be converted to alcohol and further on oxidation it gives ethanoic acid. 🔴Ethanamine reacted with nitrous acid HNO2 (prepared from …

2016年6月24日 · And thus: #LiOH(aq) + HNO_3(aq) rarr H_2O(l) + LiNO_3(aq)# #H_3PO_4(aq) + KOH(aq) rarr KH_2PO_4(aq) + H_2O(l)# #Ca(HCO_3)_2(aq) + 2HCl(aq) rarr CaCl_2(aq) …

2016年3月26日 · pK_a is a MEASURE of acidity. The more negative the pK_a, the STRONGER the acid. The generalized acid dissociation reaction in water is; HA + H_2O rightleftharpoons …

The common ion effect refers to adding to a solution at equilibrium, a salt which contains an ion in common with one of the products of that equilibrium. The effect is to shift the equilibrium …
