What happens to the concentration of Na+ when you mixed saturated NaCl and concentrated HCl (12M)?
Hydrochloric acid is sold as a concentrated aqueous solution. If the concentration of commercial is 12M and its density is 1.18g/cm3 , calculate the following: (a) the molality of the HCl solution (b) the weight percent of HCl in the solution. Please show the work on how to arrive at these answers - a. 16.2m b. 37.1%
What NaCl concentration results when 229 mL of a 0.730 M NaCl solution is mixed with 672 mL of a 0.300 M NaCl solution? concentration:
What NaCl concentration results when 219 mL of a 0.740 M NaCl solution is mixed with 537 mL of a 0.230 M NaCl solution?
NaCl(s) ⇌ Na+(aq) + Cl-(aq) ΔHo = 3.9 kJ/mol At 298 K, a saturated solution of NaCl has [Na+] = 7.0 M and [Cl-] = 5.4 M. If the temperature of the mixture is increased to 323 K, what will be the equilibrium concentration (M) of Na+? (Assume no ion pairing.) Enter your answer to 2 decimal places. NaCl(s) Na (aq) + CI'(aq) AH- 3.9 kJ/mol At 298 K, a saturated solution of NaCI has [Na"] 7.0M and [CI] -...
(a) Saturated Sodium Chloride. Watch Video-3a where to 4 mL of saturated (5.4 M) NaCl in a 13 x 100mm test tube, 2 mL of concentrated (12 M) HC) is added. Write down the chemical reaction(s) involved, being sure to include the state of matter of all reactants and products so it is clear if there is a solid/precipitate expected. (1 point) Calculate the total Cl concentration in the NaCl solution after adding 2 mL of 12 M HCl to...
For a saturated NaCl solution, what effect will adding concentrated HNO3 have on the system? Select one: a. No effect b. Shift left c. Shift right
When you are given a concentration for a compound, such as 1 M NaCl, it indicates the number of moles of formula units per liter (formula-unit concentration). By multiplying the formula-unit concentration by the number of ions per formula unit, you arrive at the ion concentration. For example, a 1 M solution of NaCl has a 2 M ion concentration (1 M of Na+ ions and 1 M of Cl− ions) because there are two ions per formula unit of...
