Aqueous sodium carbonate titration with HCl solution. When HCl solution is added slowly to the Na 2 CO 3 solution, reaction happens in two stages. When dilute HCl is slowly added, first, sodium bicarbonate and sodium chloride are formed. Na 2 CO 3 + HCl → NaCl + NaHCO 3. Sodium bicarbonate is basic and can reacts with HCl furthermore.

From the results of our studies, we conclude that even though hydrochloric acid and sodium bicarbonate react instantaneously, the resulting gas production is slow, mainly because CO2 produced from the dehydration of carbonic acid dissolves in water and is only slowly released into the gas phase.

Sodium bicarbonate reacts with hydrochloric acid in a gas-forming reaction to produce aqueous sodium chloride, water, and carbon dioxide gas: NaHCO3(s) + HCl(aq) arrow NaCl(aq) + H2O(l) + CO2(g). Determine the mass of CO2 gas produced when 8.75 g of NaHCO

HYDROCHLORIC ACID is an aqueous solution of hydrogen chloride, an acidic gas. Reacts exothermically with organic bases (amines, amides) and inorganic bases (oxides and hydroxides of metals). Reacts exothermically with carbonates (including limestone and building materials containing limestone) and hydrogen carbonates to generate carbon dioxide.

denaturation in the stomach also destroys protein function. (This is why a protein such as insulin can’t be taken as an oral medication. Its function is destroyed in the digestive tract, first by denaturation and then further by enzymatic digestion. Instead, it has to be injected so that it is absorbed intact into the bloodstream.)

Explanation: In this reaction between a metal and an acid, there are many ways to speed up this reaction. First way is to break down the magnesium ribbon into smaller pieces, so that its surface area increases, and so more acid particles can touch more places of the magnesium ribbon, therefore speeding up the reaction.
