Calculate the sodium ion concentration when 40.0 mL of 2.5 M sodium carbonate is added to 30.0 mL of 1.0 M sodium bicarbonate?
first of all, let's find the molecular formula for the two substances: Na2(CO3) and Na(HCO3).
sodium carbonate has two Na atoms in each molecule and sodium bicarbonate has only one.
now let's find the number of moles of sodium carbonate and sodium bicarbonate we have: 2.5M * .04L = .1mol
1M * .03L = .03mol
we now know that there are .2mol (.1*2) of Na in sodium carbonate because there's two sodium ions in each sodium carbonate. And we know that there's 1 Na ion in each sodium bicarbonate, so we know it's just .03 mol Na in sodium bicarbonate.
add those up: .2mol+.03mol = .23mol Na
since Molar = mol/volume, we can find the volume of the whole solution: 30mL + 40mL=70mL or .07L
.23mol/.07L is 3.29M
What else can I help you with?
Is sodium carbonate the same as sodium bicarbonate?
No, sodium carbonate (Na2CO3) and sodium bicarbonate (NaHCO3) are two different compounds. Sodium carbonate is commonly known as washing soda and is used in cleaning products, while sodium bicarbonate is known as baking soda and is often used in baking and as an antacid.
Is sodium bicarbonate the same as sodium carbonate?
No, sodium bicarbonate (baking soda) and sodium carbonate (soda ash) are different compounds with distinct chemical compositions. Sodium bicarbonate is commonly used in baking and as an antacid, while sodium carbonate is used in making glass, detergents, and other industrial processes.
How do you make 0.05M carbonate-bicarbonate?
for 500ml 0,05M solution take Na2CO3#1.59gm NaHCO3#2.93 ph#9.6
What is the bi in bicarbonate?
It is actually Hydrogen. Sodium Bicarbonate is properly known as Sodium Hydrogen Carbonate, and sometimes Sodium Acid Carbonate (Hydrogen makes it an acid)CompareNaHCO3 (sodium bicarbonate)Na2CO3 (sodium carbonate)Since sodium carbonate takes two sodium ions for each carbonate, and bicarbonate has only one, ratio of carbonate ions to sodium ion doubles, hence the term bicarbonate.
What are the products from the decomposition of sodium bicarbonate?
When sodium bicarbonate decomposes, it forms water, carbon dioxide, and sodium carbonate. Heating sodium bicarbonate causes it to break down into these products.
When sodium Bicarbonate decomposes it produce sodium carbonate and what else?
Sodium bicarbonate decomposes into sodium carbonate, carbon dioxide, and water.
Is sodium carbonate the same as sodium bicarbonate?

for 500ml 0,05M solution take Na2CO3#1.59gm NaHCO3#2.93 ph#9.6
Is the sodium bicarbonate the same as sodium carbonate?
No; sodium carbonate is Na2CO3, with two sodium ions, while sodium bicarbonate is NaHCO3 and has a hydrogen ion instead of a sodium ion.
What is the bi in bicarbonate?
It is actually Hydrogen. Sodium Bicarbonate is properly known as Sodium Hydrogen Carbonate, and sometimes Sodium Acid Carbonate (Hydrogen makes it an acid)CompareNaHCO3 (sodium bicarbonate)Na2CO3 (sodium carbonate)Since sodium carbonate takes two sodium ions for each carbonate, and bicarbonate has only one, ratio of carbonate ions to sodium ion doubles, hence the term bicarbonate.

When sodium bicarbonate decomposes, it forms water, carbon dioxide, and sodium carbonate. Heating sodium bicarbonate causes it to break down into these products.
Is sodium bicarbonate and corn starch the same?
No, Sodium carbonate (Na2CO3) is washing soda. It is a stronger base (more alkaline) than sodium bicarbonate (NaHCO3) or baking soda. Sodium bicarbonate may also be called sodium hydrogen carbonate.
What is the difference between the masses of sodium bicarbonate and calcium carbonate?
The mass of sodium bicarbonate (NaHCO3) is 84 grams/mol, while the mass of calcium carbonate (CaCO3) is 100 grams/mol. Therefore, calcium carbonate has a higher molecular mass compared to sodium bicarbonate.
Chemical formula of sodium carbonate?
Sodium carbonate is Na2CO3(the more familiar compound, baking soda, is sodium bicarbonate, NaHCO3)
What is a chemical name for sodium bicarbonate?
sodium hydrogen carbonate
Is sodium carbonate a liquid?
No, both sodium carbonate (washing soda) and sodium bicarbonate (baking soda) are solids.
