We are doing a lab that requires finding the molarity of an unknown AgNO3 solution after reacting NaCl + AgNO3 --> NaNO3 and AgCl and collecting/massing the precipitate. We will be using 10.00 mL of an NaCl solution and 10.00 mL of the AgNO3 solution. We know that the AgNO3 concentration will lie somewhere between .150M and .350M.

My lab partner want to find out what the molarity of the NaCl solution needs to be so that we react the exact amount of AgNO3 given. I know this will probably end up being an exact reacting ratio problem- but is it possible to figure out with the information given? If so, can someone show me how to do a problem like this?

Take the balanced equation:
NaCl + AgNO3 --> NaNO3 and AgCl

So one wants the same number of moles of sodium chloride as silver nitrate, so if you use equal volumes, then EQUAL concentrations need to be used.

the answer is 7

What is the same and different in the following ionic compounds?
A) Na2SO4 and BaSO4

B) AgNO3 and AgCl

A- different

B- same

To determine the similarities and differences between the ionic compounds Na2SO4 and BaSO4, as well as AgNO3 and AgCl, we need to consider the composition and properties of each compound.

A) Na2SO4 and BaSO4:

1. Composition:
- Na2SO4: This compound contains sodium (Na) ions and sulfate (SO4) ions. It consists of two sodium ions and one sulfate ion.
- BaSO4: This compound contains barium (Ba) ions and sulfate (SO4) ions. It consists of one barium ion and one sulfate ion.

2. Similarities:
- Both compounds contain sulfate (SO4) ions.

3. Differences:
- The cations (positively charged ions) differ between the compounds. Na2SO4 has sodium ions (Na+), whereas BaSO4 has barium ions (Ba2+).
- The ratio of cations to anions is different. Na2SO4 has a 2:1 ratio of sodium ions to sulfate ions, while BaSO4 has a 1:1 ratio of barium ions to sulfate ions.

B) AgNO3 and AgCl:

1. Composition:
- AgNO3: This compound contains silver (Ag) ions and nitrate (NO3) ions. It consists of one silver ion and one nitrate ion.
- AgCl: This compound contains silver (Ag) ions and chloride (Cl) ions. It consists of one silver ion and one chloride ion.

2. Similarities:
- Both compounds contain silver (Ag) ions.

3. Differences:
- The anions (negatively charged ions) differ between the compounds. AgNO3 has nitrate ions (NO3-), whereas AgCl has chloride ions (Cl-).

In summary, the compounds Na2SO4 and BaSO4 have similar sulfate ions but different cations and ratios of cations to anions. The compounds AgNO3 and AgCl have similar silver ions but different anions.

A) Na2SO4 and BaSO4 both contain the sulfate ion (SO4^2-) and are ionic compounds. However, they have different cations. Na2SO4 contains sodium ions (Na+), while BaSO4 contains barium ions (Ba^2+).

B) AgNO3 and AgCl both contain the silver ion (Ag+) and are also ionic compounds. However, they have different anions. AgNO3 contains the nitrate ion (NO3^-), while AgCl contains the chloride ion (Cl^-).
