How can it be classified that the gas given is carbon dioxide when dilute hydrochloric and sodium carbonate reacts?
When dilute hydrochloric acid is added to sodium carbonate solution, it produces bubbles of carbon dioxide gas. This can be tested by passing the gas through limewater, which will turn milky if carbon dioxide is present. Additionally, the gas can be identified using a flame test, where carbon dioxide does not support combustion.
How do you make anhydrous sodium carbonate?
Anhydrous sodium carbonate, also known as soda ash or washing soda, can be made by heating hydrated sodium carbonate to drive off the water. This can be done by heating sodium carbonate decahydrate (washing soda) at a temperature above 250°C until it is completely dehydrated, leaving behind anhydrous sodium carbonate.
How do you determine whether sodium carbonate is present?
Sodium carbonate can be identified by performing a flame test, which results in a yellow flame. Additionally, you can conduct a simple solubility test by dissolving the compound in water, which will result in a basic solution due to the presence of the carbonate ion. Finally, you can confirm the presence of sodium carbonate using analytical techniques such as titration with acid to determine the sodium carbonate concentration.
Why does sodium carbonate not decompose when heated using?
Sodium carbonate does decompose when heated, but it requires a high temperature of around 851°C. At this temperature, sodium carbonate decomposes to form sodium oxide and carbon dioxide gas. Lower temperatures may not provide enough energy for the chemical reaction to occur visibly.
How much calcium carbonate in grams can be dissolved by 5.00 grams of hydrochloric acid?
The molar mass of calcium carbonate is 100.09 g/mol and the molar mass of hydrochloric acid is 36.46 g/mol. Using the mole ratio of the balanced chemical equation, you can calculate the amount of calcium carbonate that can be dissolved by 5.00 grams of hydrochloric acid, which is approximately 12.43 grams.
What is the Frame structure of Serial Line Internet Protocol?
Preparation of standard solution and standardization of hydrochloric acid Objective : To prepare a standard solution of sodium carbonate and use it to standardize a given solution of dilute hydrochloric acid. Introduction : Anhydrous sodium carbonate is a suitable chemical for preparing a standard solution (as a primary standard). The molarity of the given hydrochloric acid can be found by titrating it against the standard sodium carbonate solution prepared. The equation for the complete neutralization of sodium carbonate with dilute hydrochloric acid is Na2CO3(aq) + 2HCl(aq) → 2NaCl(aq) + CO2(g) + H2O(l) The end-point is marked by using methyl orange as indicator. Chemicals :solid sodium carbonate, 0.1 M hydrochloric acid

Why Na2Co3 extract is not used for carbonate test?
Na2CO3 extract is not used for carbonate test because it is a carbonate compound itself (sodium carbonate). Using it in the test would not provide a valid result, as it would already contain carbonate ions. To test for carbonate ions, a substance that does not already contain carbonate, such as hydrochloric acid, is used.
What experiment can you do to find out how much calcium carbonate there is in limestone?
To determine the amount of calcium carbonate in limestone, you can perform a titration using hydrochloric acid. By reacting a known mass of limestone with hydrochloric acid, you can measure the volume of acid required to neutralize the calcium carbonate. This information can then be used to calculate the amount of calcium carbonate present in the limestone sample.

Need Help with my pH calculation?
1) 0.10 mol of solid sodium hydrogen carbonate and 0.20 mol of solid sodium carbonate are dissolved in the same beaker of water, transferred to a volumetric flask and made to 250.0 mL. The Ka for HCO3 - is 4.7 x 10-11. a) What is the pH of the resulting buffer? b) What is the pH of solution after 20.00 mL of 0.050 mol L-1 hydrochloric acid solution is added to 25.00 mL of the original solution? c)What is the pH of the resulting buffer after 0.040 g of solid sodium hydroxide is added to 25.00 mL of the original solution? 2) Plan how you would make 100.0 mL of a buffer solution with a pH of 10.80 to be made using only sodium carbonate, sodium hydrogen carbonate and water.Youshould specify the amounts of sodium carbonate and sodium hydrogen carbonate that you would use. ( the ration acid to base is 3:1)

How could you determine whether a white powder was zinc sulfide or sodium carbonate using a hydrochloric acid solution?
Silver nitrate would not react with HCl while Zinc Sulphide would react with HCl forming Zinc Chloride and evolving H2S gas. AgNO3 +HCl---> No reaction ZnS + 2HCl -------> ZnCl2 + H2S
Why does sodium carbonate not decompose when heated using a Bunsen burner?
Sodium carbonate does decompose when heated, it undergoes thermal decomposition to form sodium oxide (Na2O), carbon dioxide (CO2), and water (H2O). However, the decomposition of sodium carbonate is not easily noticeable when using a Bunsen burner as the high temperature and rapid combustion of the gas can mask the decomposition reaction.
Does sodium carbonate react with phenolphthalein indicator?
Sodium carbonate does react with phenolphthalein indicator, producing a color change from colorless to pink in alkaline solutions. Sodium carbonate is a common base that can be used to test for the presence of acidity or alkalinity in a solution using phenolphthalein.
