Nitric acid reaction with potassium

A Write the formula unit equations, the total ionic equations, and net ionic equations for the reactions of nitric acid, HNO3, with potassium hydroxide, KOH, and of carbonic acid, H2CO3, with potassium hydroxide, KOH. What differences do you observe between the net ionic equation for the reaction of nitric acid, a strong acid, with a strong base and the net ionic equation for the reaction of carbonic acid, a weak acid, with a strong base ... 

Nitric acid reacts with all metals except gold, iridium, platinum, rhodium, tantalum, titanium, and certain alloys. It reacts violentiy with sodium and potassium to produce nitrogen. Most metals are converted iato nitrates arsenic, antimony, and tin form oxides. Chrome, iron, and aluminum readily dissolve ia dilute nitric acid but with concentrated acid form a metal oxide layer that passivates the metal, ie, prevents further reaction. 

Sodium Nitroprusside, Na2Fe(CN)5NO (22.6.7) It is synthesized by successive reactions including the reaction of potassium ferrocyanide with nitric acid, which forms potassium nitroprusside (22.6.5), which is further transformed to copper nitroprusside (22.6.6), and reaction of this with sodium carbonate gives sodium nitroprusside (22.6.7). 

Among some important industrial reactions of sulfuric acid is its reaction with potassium nitrate and distillation of nitric acid from the mixture ... 

HCNO (aq.). Berthelot27 measured the heat of reaction of aqueous potassium cyanate with aqueous hydrochloric acid, and Lemoult1 that of aqueous barium cyanate with aqueous nitric acid and with aqueous sulfuric acid. 

The trinitro-m-toluidine thus obtained is oxidized in sulphuric acid solution with potassium persulphate. The yield of this stage of the reaction is about 85% of theory. The tetranitrotoluene thus prepared may then be recrystallized from nitric acid of a sp. gr. of 1.40. 

A saturated aqueous solution boils at 103° C. The aqueous solution exhibits an acid reaction with litmus paper, has a shaiqi, metallic taste, and is, of course, poisonous (see p. -15). It absorbs nitric oxide with eventual precipitation of chromium dioxide. Unlike the normal salt, potassium dichromate is strongly adsorbed in solution by animal charcoal. ... 

Consider the neutralization reaction that takes place when nitric acid reacts with aqueous potassium hydroxide. 

To a chemist, the term salt refers to the ionic product of a neutralization reaction, the positive ion coming from the base (K+ from KOH), and the negative ion coming from the acid (Cl from HCl). Potassium chloride, KCl, is the salt produced in the neutralization of hydrochloric acid and potassium hydroxide. Sodium nitrate, NaN03, is the salt produced in the neutralization of nitric acid, HN03, with sodium hydroxide, NaOH. The other product, water, is the covalent product of neutralization, formed by the combination of H+ from the acid, and OH , from, the base. Notice now the ions responsible for the properties of acids, H (aq), and the properties of bases, OH (aq), combine to form neutral water, HzO(I). This is how acids and bases destroy the properties of each other simultaneously. 

MERCURIC THIOCYANATE (592-85-8) Hg(SCN)i Moderately unstable solid. Possible violent reaction with strong oxidizers strong acids organic peroxides, peroxides and hydroperoxides potassium chlorate potassium iodate, silver nitrate, sodium chlorate, nitric acid. Incompatible with ammonia, chlorates, hydrozoic acid, methyl isocyanoacetate, nitrates, nitrites, perchlorates, sodium peroxyborate, trinitrobenzoic acid, urea nitrate. When heated, this material swells to many times its original bulk. Attacks aluminum in the presence of moisture. Decomposes above 329°F/165°C, releasing toxic mercury and cyanide fumes, and sulfur and nitrogen oxides. On small fires, use dry chemical powder (such as Purple-K-Powder), alcohol-resistant foam, or COj extinguishers. MERCURIC (Spanish) (7439-97-6) see mercury. 

SODIUM RHODANIDE (540-72-7) NaSCN Exposure to light causes slow decomposition, forming cyanide, sulfur oxides, and nitrous vapors. Violent reaction, possibly explosion, with strong oxidizers, organic peroxides, nitric acid. Incompatible with acids, bases, chlorates, anunonia, amines, amides, alcohols, glycols, caprolactam, nitrates, peroxides and hydroperoxides, potassium chlorate, potassium iodate, silver nitrate, sodium chlorate. Contact with sulfuric acid forms toxic carbonyl sulfide gas. Forms explosive mixture with sodium nitrate. Thermal decomposition releases oxides of sulfur and nitrogen.
