Question

When a saturated solution of NH4Br dissolved in 100 grams of water is cooled from 60°C to 30°C, how much NH4Br will precipitate?

Answer 1

`m_(precipitated)=24.8g`

Step-by-step explanation:

Hello,

In this case, since at 60 °C, 108 grams of ammonium bromide are completely dissolved in 100 grams of water for a saturated solution, once it is cooled to 30 °C, wherein only 83.2 grams are completely dissolved in 100 grams of water, the following mass will precipitate:

`m_(precipitated)=108g-83.2g\\\\m_(precipitated)=24.8g`

Best regards.
