Answer:

Answer:HERE IS YOUR ANSWER

Answer:HERE IS YOUR ANSWERExplanation:

Answer:HERE IS YOUR ANSWERExplanation:(a) At 313 K 62 g of potassium nitrate dissolved in 100 g of water. So to produce a saturated olution of potassium nitrate in 50 g of water we need 62/100×50=31 g of potassium nitrate.

×50=31 g of potassium nitrate.(b)Some soluble potassium chloride will separate out in the form of crystal at room temperature because the solubility of potassium chloride will decrease.

×50=31 g of potassium nitrate.(b)Some soluble potassium chloride will separate out in the form of crystal at room temperature because the solubility of potassium chloride will decrease.(c)

×50=31 g of potassium nitrate.(b)Some soluble potassium chloride will separate out in the form of crystal at room temperature because the solubility of potassium chloride will decrease.(c)(i) Solubility of Potassium nitrate at 293 K is 32 g.

×50=31 g of potassium nitrate.(b)Some soluble potassium chloride will separate out in the form of crystal at room temperature because the solubility of potassium chloride will decrease.(c)(i) Solubility of Potassium nitrate at 293 K is 32 g.(ii) Solubility of sodium chloride at 293 K is 36 g.

×50=31 g of potassium nitrate.(b)Some soluble potassium chloride will separate out in the form of crystal at room temperature because the solubility of potassium chloride will decrease.(c)(i) Solubility of Potassium nitrate at 293 K is 32 g.(ii) Solubility of sodium chloride at 293 K is 36 g.(iii) Solubility of Potassium chloride at 293 K is 35 g.

×50=31 g of potassium nitrate.(b)Some soluble potassium chloride will separate out in the form of crystal at room temperature because the solubility of potassium chloride will decrease.(c)(i) Solubility of Potassium nitrate at 293 K is 32 g.(ii) Solubility of sodium chloride at 293 K is 36 g.(iii) Solubility of Potassium chloride at 293 K is 35 g.(iv) Solubility of Ammonium chloride at 293 K is 37 g.

×50=31 g of potassium nitrate.(b)Some soluble potassium chloride will separate out in the form of crystal at room temperature because the solubility of potassium chloride will decrease.(c)(i) Solubility of Potassium nitrate at 293 K is 32 g.(ii) Solubility of sodium chloride at 293 K is 36 g.(iii) Solubility of Potassium chloride at 293 K is 35 g.(iv) Solubility of Ammonium chloride at 293 K is 37 g. The solubility of Ammonium chloride is highest at this temperature.

×50=31 g of potassium nitrate.(b)Some soluble potassium chloride will separate out in the form of crystal at room temperature because the solubility of potassium chloride will decrease.(c)(i) Solubility of Potassium nitrate at 293 K is 32 g.(ii) Solubility of sodium chloride at 293 K is 36 g.(iii) Solubility of Potassium chloride at 293 K is 35 g.(iv) Solubility of Ammonium chloride at 293 K is 37 g. The solubility of Ammonium chloride is highest at this temperature.(d)The solubility of salt increases with the increase in temperature.
