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.
How do you balance this equation caoh2 plus na2co3 plus hno3?
The balanced chemical equation is Ca(OH)2 + Na2CO3 + 2HNO3 → Ca(NO3)2 + 2NaOH + CO2 + H2O
How do you balance the equation NH4Cl plus Na2CO3 equals NH3 plus CO2 plus H2O plus NaCl?
2NH4Cl + Na2CO3 --> 2NH3 + CO2 + H2O + 2NaCl
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.
What is the KB of Na2CO3?
The molar mass of Na2CO3 (sodium carbonate) is approximately 105.99 g/mol. To calculate the KB, you would first look up the pKa values for the conjugate acid (HCO3-) and then use the relation KB = Kw / Ka.

How many points is a sack in the end zone?
2, a sack in the end zone is considered a safety which is 2 points
How do you balance this equation caoh2 plus na2co3 plus hno3?
The balanced chemical equation is Ca(OH)2 + Na2CO3 + 2HNO3 → Ca(NO3)2 + 2NaOH + CO2 + H2O
Which number belongs in the blank in order for this to be a balanced equation Na2CO3 plus CaCl2 NaCl plus CaCO3?
The answer is TWO (2)Na2CO3 + CaCl2 --> 2 NaCl + CaCO3
Equation for copper nitrate and sodium carbonate?
The balanced chemical equation for the reaction between copper(II) nitrate (Cu(NO3)2) and sodium carbonate (Na2CO3) is: Cu(NO3)2 + Na2CO3 → CuCO3 + 2NaNO3
What is the endpoint of 7 2?
The end points are 7 and 2.
How do you balance the equation NH4Cl plus Na2CO3 equals NH3 plus CO2 plus H2O plus NaCl?
2NH4Cl + Na2CO3 --> 2NH3 + CO2 + H2O + 2NaCl
What is between 2 points?
A line segment is between two end points
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 shape has 2 end points?
The shape that has 2 end points is known as a line segment. A line segment is a line that can go on forever, but it has a start point and an end point, no matter where it stops.
