What is a chemical equation for the dissociation of a soluble salt in water?
An example is the dissociation of NaCl in water: NaCl (s) -> Na+ (aq) + Cl- (aq). Here, NaCl breaks apart into its constituent ions, Na+ and Cl-, when dissolved in water due to the attraction between the ions and water molecules.
How mny moles are in 23.34 of NaCl?
I'm going to assume that you mean 23.34g of NaCl. 1 mole NaCl = 58.442g NaCl (the atomic weight of Na and Cl in grams) 23.34g NaCl x (1mol NaCl/58.442g NaCl) = 0.3994mol NaCl
Is NaCl compound or molecule?
NaCl is a compound, not a molecule. This is because NaCl is created when the elements sodium (Na) and chlorine (Cl) chemically bond together to form a new substance with different properties from its individual elements.
How many total number of atoms are in NaCl?
The atomic number of Sodium (Na) is 11.The atomic number of Chlorine (Cl) is 17.There are one Sodium ion (Na+) and one Chloride ion (Cl-) in every Sodium Chloride (NaCl) molecule.
What ions are in NaCl?
A sodium ion. Cation. Na+ A chlorine ion. Anion Cl- Forms NaCl, sodium chloride.
How many ppm of Na in 100 ppm NaCl?
Since NaCl is composed of one Na atom and one Cl atom, and the molar mass of Na is roughly 23 g/mol while that of Cl is about 35.5 g/mol, the molar mass of NaCl is approximately 58.5 g/mol. In 100 ppm NaCl, there are 100 mg of NaCl in 1 kg of solution. Therefore, the amount of Na in 100 ppm NaCl would be 100 mg * (23 g Na / 58.5 g NaCl) = ~ 39.3 ppm Na.
Is 100 ppm solution of NaCl means 100 ppm of Na?
No, a 100 ppm NaCl solution means there are 100 parts per million of NaCl (sodium chloride) in the solution, not just sodium (Na) alone. To calculate the amount of sodium ions (Na+) in the solution, you would need to consider the molar mass of NaCl and the percentage of Na+ in NaCl.
How do you prepare 100ml of 1000ppm Na from NaCl?
1ppm = 1mg/lso, 1000ppm = 1gm/l or 0.1gm/100ml that is your required.FW of NaCl = 58.5 (Na-23+Cl-35.5)58.5gm NaCl = 23gm NaXgm NaCl = 0.1gm Natherefor X = 0.2543gmSo dissolve 0.2543gm of NaCl to 100ml, to get 1000ppm of 100ml Na soln.
How do you make 1000ppm standard of Na using the salt NaCl?
To make a 1000 ppm Na standard solution using NaCl, you would dissolve 0.0585 grams of NaCl (molecular weight of NaCl = 58.44 g/mol) in 1 liter of water. This would give you a solution with a concentration of 1000 ppm Na.
Preparation of 1000ppm of standard Sodium solution from NaCl?
1 mg/l = 1ppm1 g/l = 1000 ppmNaCl ----------------> Na+ + Cl-58.5 g NaCl gives 22.989 g Na+(58.5 / 22.989) = 2.545 g of NaCl is required to give 1 g of Na+When 2.545 g of NaCl is dissolved in 1 liter water will yield 1000 ppm of Na+ in NaCl solution.
What is the cation for NaCl?
The cation, or positively charged ion, in NaCl is Na+.
What happens with dissociation in NaCl?
The equation is: NaCl----------Na++ Cl-
What is the dissocociation of NaCl to Na Cl?
NaCl---------------→Na+ + Cl-
Na+ and Cl- are ions formed from?
Na+ + Cl- --> NaCl NaCl = salt.
What is the dissociation equation for NaCl?
NaCl --> Na+ + Cl- You could write water on either side I suppose, but it is negligible. I've also seen H2O written over the arrow.
What is weight of na in 348 grams of nacl?
[348 (g NACl)] * [23 (g/mol Na)] * [1 (mol NaCl/mol Na)] / [58.5 (g/mol NaCl)] = [348*23/58.5] = 136.8 = 137 g Na
What is the number of grams of sodium in 8.0g of NaCl?
In NaCl, the molar mass of Na is 22.99 g/mol and Cl is 35.45 g/mol. Therefore, the molar mass of NaCl is 58.44 g/mol. Given 8.0g of NaCl, the mass is distributed between Na and Cl in a 1:1 ratio. Thus, there are 3.5g of Na in 8.0g of NaCl.
