Sodium hydrogen carbonate NaHCO

That hydrogen is present in an acid is implied in the name by the word acid, not by the word hydrogen . For example, HCl is hydrochloric acid. The word hydrogen is used in names of acid salts, such as sodium hydrogen carbonate, NaHCOs. 

Chemicals and solutions. Aqueous salt solutions were prepared from water purified through reversed osmosis (conductivity 5 to 10 pS/cm at 25 °C). The following salts were used calcium chloride tetrahydrate, CaCl24H20 (Merck Suprapur), sodium hydrogen carbonate, NaHCO, (Merck p.a.) and sodium chloride, NaCl (Merck Suprapur) as supporting electrolyte. Carbon dioxide, C02(g) was of analytical grade. 

Although antacids contain other ingredients, all antacids contain a base that counteracts stomach acid. The base is either sodium hydrogen carbonate, NaHCOs, calcium carbonate, CaCOs, aluminum hydroxide, Al(OH)c , or magnesium hydroxide, Mg(OH)2. 

To standardize a hydrochloric acid solution, it was used as titrant with a solid sample of sodium hydrogen carbonate, NaHCOs. The sample had a mass of 0.3967 g, and 41.77 mL of acid was required to reach the equivalence point. Calculate the concentration of the standard solution. 

Sodium hydrogen carbonate (NaHCOs), commonly known as baking soda, is also called sodium bicarbonate. 

Figure 9.19 When vinegar and baking soda (sodium hydrogen carbonate, NaHCOs) combine, the resuit is a vigorous bubbling that releases carbon dioxide (CO2). 

Use a balance to measure the mass of a clean, dry crucible. Add about 3.0 g of sodium hydrogen carbonate (NaHCOs). and measure the combined mass of the crucible and NaHCOs. Record both masses in your data table, and calculate the mass of the NaHCOs. 

Baking soda (sodium hydrogen carbonate, NaHCOs) is often used to neutralize spills of acids on the benchtop in the laboratory. What mass of NaHC03 would be needed to neutralize a spill consisting of 25.2 mL of 6.01 M hydrochloric acid solution ... 

Practice Exercise How would you prepare a hter of carbonate buffer at a pH of 10.10 You are provided with carbonic acid (H2CO3), sodium hydrogen carbonate (NaHCOs), and sodium carbonate (Na2C03). See Table 15.5 for values. 

Carbon dioxide is used for the manufacture of sodium carbonate, NagCOs-lOHaO (washing soda) sodium hydrogen carbonate, NaHCO.- (baking soda) and carbonated water, for use as a beverage (soda water). Carbonated water is charged with carbon dioxide under a pressure of 3 or 4 atm. 

When baking soda (sodium bicarbonate or sodium hydrogen carbonate, NaHCOs) is heated, it releases carbon dioxide gas, which is responsible for the rising of cookies, donuts, and bread, (a) Write a balanced equation for the decomposition of the compound (one of the products is Na2C03). (b) Calculate the mass of NaHC03 required to produce 20.5gofCC>2. 

Practice Problem A Identify the following compounds as nonelectrolytes, weak electrolytes, or strong electrolytes ethanol (C2H5OH), nitrous acid (HNO2), and sodium hydrogen carbonate (NaHCOs, also known as bicarbonate). 

The percentage of sodium hydrogen carbonate, NaHCOs, in a powder for stomach upsets is found by titrating with 0.275 M hydrochloric acid. If 15.5 mL of hydrochloric acid is required to react with 0.500 g of the sample, what is the percentage of sodium hydrogen carbonate in the sample ...
