Give two uses of `Na_2CO_(3)`.

Which of the following may be a use of Na_(2)CO_(3).10H_(2)O ?

Which of the following gives equivalent mass of Na_(2)CO_(3) when titrated against HCl in the presence of methyl orange ?

Standardization of Acid Solution: Calculate the normality of a solution of H_(2)SO_(4) if 40.0 mL of the solution reacts completely with 0.364 gram of Na_(2)CO_(3) . Strategy: Refer to the balanced equation. We are given the mass of Na_(2)CO_(3) , so we convert grams of Na_(2)SO_(3) to equivalents of Na_(2)CO_(3) , then to equivalents of H_(2)SO_(4) , which let us calculate the normality of the H_(2)SO_(4) solution.

A mixture contains two moles of Na_(3)CO_(3) and 1 mole of Li_(2)CO_(3) . What will be the volume of CO_(2) formed on heating this mixture and the data is converted to STP?

0.1g of a solution containing Na_(2)CO_(3) and NaHCO_(3) requires 10mL of 0.01 N HCl for neutralization using phenolphthalein as an indicator, mass% of Na_(2)CO_(3) in solution is:

consider the following reaction, Na_(2)CO_(3) + 2HCl to 2NaCl + H_(2)O + CO_(2) Equivalent weight of Na_(2)CO_(3) is

Write the chemical name of Na_(2)CO_(3).10H_(2)Oand Na_(2)CO_(3). Writer the significance of 10H_(2)O. Mention the term used for wate molecules attached with a slat. With the help of chemical equation explain the method of preparation of both Na_(2)CO_(3).10H_(2)O and Na_(2)CO_(3). Also list two uses of Na_(2)CO_(3).10H_(2)O.
