What happens when a titration is done with Na2co3 in the biurrette and h2so4 in the flask?

When titrating Na2CO3 with H2SO4, the acid-base reaction that occurs is: Na2CO3 + H2SO4 → Na2SO4 + H2CO3 The carbonate ion (CO3^2-) in Na2CO3 reacts with the hydrogen ion (H+) in H2SO4 to form carbonic acid (H2CO3), which then decomposes into water (H2O) and carbon dioxide (CO2). The endpoint of the titration is reached when all the Na2CO3 has reacted with the H2SO4.

What is the coefficient for na2co3 cacl2 caco3 nacl?

The balanced chemical equation for the reaction between Na2CO3 and CaCl2 to form CaCO3 and NaCl is: Na2CO3 + CaCl2 -> CaCO3 + 2NaCl. Therefore, the coefficients are 1, 1, 1, and 2 for Na2CO3, CaCl2, CaCO3, and NaCl respectively.


What is the balanced equation of Caci2 and Na2cO3?

First it's CaCl2, with a lowercase L, not an i. The balanced equation is: Na2CO3(aq) + CaCl2(aq) --> 2NaCl(aq) + CaCO3(s)


What volume of 0.100 M HCl is required to completely react with ml of 0.161 M Na2CO3?

To solve this problem, we need to use the balanced chemical equation between HCl and Na2CO3. From the equation, we can see that it is a 1:2 ratio for HCl to Na2CO3. Therefore, we need twice the volume of 0.161 M Na2CO3 to react completely with HCl. Calculate the volume of HCl required by multiplying the volume of Na2CO3 by 2.


If the reactants are 2agclo3 and na2co3 what are the products?

The reaction between 2 AgClO3 and Na2CO3 produces silver carbonate (Ag2CO3) and sodium chloride (NaCl). The balanced equation for the reaction is: 2 AgClO3 + Na2CO3 → Ag2CO3 + 2 NaCl. This reaction is a double displacement reaction where the cations and anions exchange partners.
