Is 0.9 NaCl and NaCl the same?
NaCl is the formula unit of sodium chloride; 0,9 NaCl is a solution, probable o,9 molar.
What are the chemical or physical differences between KCl plus NaBr solution and KBr plus NaCl solution of same molar density?
When you flame test the two solutions, any Na solution burns yellow, while any K solution burns violet/purple. So both the KCl and the KBr will burn purple, while both NaBr and NaCl will burn yellow.
How is a 5 molar solution different than a 1 molar solution of koolaid?
They're actually exactly the same in that neither of them exists.
What is the total dilution factor from 1.00 M NaCl to 1.00 M NaCl solution?
The concentration is the same !
A solution that contains the same level of NaCl as that found in red blood cells is called?
isotonic solution
How do 0.5M and 2.0M aqueous solutions of NaCl differ?
The 0.5M solution has a lower concentration of NaCl compared to the 2.0M solution. This means the 2.0M solution has more NaCl dissolved in the same volume of water. Consequently, the 2.0M solution will be more concentrated and have a higher osmolarity compared to the 0.5M solution.
How man meq of Na in 150ml of 0.9 percent NaCl?
There are 150 mg of Na in 1 ml of 0.9% NaCl solution. This is equivalent to 150 mEq of Na in 150 ml of the same solution.
How many atoms of Na are in 49.3g of NaCl?
There is 1 atom of Na in 1 molecule of NaCl. The molar mass of NaCl is 58.44 g/mol, so in 49.3g there are 49.3/58.44 moles of NaCl. This equals the same number of moles of Na, which corresponds to 49.3/58.44 x 6.022 x 10^23 atoms of Na.
Is molarity equivalent to molar equivalent?
No, molarity and molar equivalent are not the same. Molarity is a measure of the concentration of a solute in a solution expressed as moles of solute per liter of solution, while molar equivalent is a concept used in stoichiometry to express the relative amounts of reactants and products involved in a chemical reaction.
How should the pH of a 0.1 molar solution of nac2h3o2 compare with that of a 0.1 molar solution of kc2h3o2?
The pH of the 0.1 M solution of NaC2H3O2 would be higher than that of the 0.1 M solution of KC2H3O2 as NaC2H3O2 is a strong base and will increase the pH, while KC2H3O2 is a weak acid and will decrease the pH.
Will elevation in boiling point be same for 0.1 m NaCl and 0.1m sucrose solution?
No, the elevation in boiling point will not be the same for a 0.1 m NaCl solution and a 0.1 m sucrose solution. This is because the elevation in boiling point is directly proportional to the number of particles in the solution, known as the van't Hoff factor. NaCl dissociates into two ions (Na+ and Cl-) in solution, so it has a van't Hoff factor of 2, while sucrose does not dissociate and has a van't Hoff factor of 1. Therefore, the NaCl solution will have a greater elevation in boiling point compared to the sucrose solution.
What is the normality of the solution which is prepared by the adding 100g NACL in 1 liter of solution?
For NaCl [note correct capitalization], normality is the same as molarity, the number of moles or, for ionically bonded compounds such as NaCl, gram formula masses per liter of solution, because the ions produced from NaCl in water are monovalent. The gram formula mass of NaCl is 58.44. Therefore 100 g of NaCl constitute 100/58.44 or 1.71 gram formula masses, to the justified number of significant digits. If the final volume of the solution is 1 litre, this is also the normality. If the volume is not considered exact, only one significant digit would be justified for normality, which should then be specified as 2.
