A small amount of salt dissolved in water is an example of a homogeneous mixture
Explanation :
here small amount of salt dissolved completely in water. so it has same composition through out the mixture.
so this is homogeneous mixture.
The maximum amount of salt that can be dissolved in water at 100C is 391g/L. Calculate the molar concentration in this case, knowing that 1 mole of water has 18g and 1 mole of salt has 58.5g.
The maximum amount of salt that can be dissolved in water at 0C is approximately 350g/L. Calculate the freezing temperature of the saturated solution.
34. When salt was mixed with water and petroleum ether, salt dissolved in water but not in petroleum ether. This was because water is polar and salt is polar petroleum ether is polar and salt is polar petroleum ether is non-polar and salt is non-polar
6. Enough of a sparingly soluble salt AB(s) dissolved in a certain amount of water to bring it into equilibrium with the ions A" (aq) and B (aq). If the equilibrium concentration of A*? is 4.9 x 10 mol kg"', and the Debye Hückel Limiting Law (DHLL) is obeyed at this concentration, K sp for the salt is: A) 2.11e-9 B) 4.90e-9 C) 4.86e-10 D) 8.46e-9 E) 3.91e-10
A small of methanol (CH_3OH) is dissolved in a large amount of water. Imagine separating this process into the four stages sketched below. (These sketches show only a portion of the substances, so you can see the density and distribution of atoms and molecules in them.) Use these sketches to answer the questions in the table below
A tank initially contains 500 gallons of water in which 40 pounds of salt is initially dissolved in the water. Brine (a water-salt mixture) containing 0.4 pounds of salt per gallon flows into the tank at the rate of 5 gal/min, and the mixture (which is assumed to be perfectly mixed) flows out of the tank at the same rate of 5 gal/min. Let y(t) be the amount of salt (in pounds) in the tank at time t. a) Set up...
In the United States, table salt is “iodized” and contains NaCl and a small amount of KI. The iodide was added to help prevent thyroid disorders in the population. The iodide concentration in table salt was measured using the following steps: 1.000 g of table salt was dissolved in 100.0 mL of water. The salt solution was titrated using 4.00 × 10−5 M Ag+ and a Volhard titration (back titration). 15.00 mL of 4.00 × 10−5 M Ag+ solution was...
An unknown acid salt was dissolved in water and titrated with 0.105 M NaOH. If 1.20 grams of the salt were dissolved and it took 120 mL to reach the equivalence point, what is the unknown? ( )NaF ( ) NH4Cl ( ) (CH3)3NHCl ( ) NaHCO3
(1 point) A tank holds 250 gallons of water than contains 50 pounds of dissolved salt. Pure water is flowing into the tank at the rate of 1/2 gal/min while the solution flows out of the tank at the rate of 4 gal/min. (a) Write down a differential equation describing this situation. Use y for the amount of salt in the tank dy 4y/250-3.5t) dt (b) Write this equation in the correct form for using the method of separation of...
A small amount of sodium bromide (NaBr) is dissolved in a large amount of water. Imagine separating this process into the four stages sketched below. (These sketches show only a portion of the substances, so you can see the density and distribution of atoms and molecules in them.) NaBr solution Use these sketches to answer the questions in the table below is negative The enthalpy of solutionAH NaBr dissolves in water. Use this information to list the stages in order...
