Question

1. Explain the process used for removing impurities from common salt​

Answer 1

Answer:

The most obvious and simple way ofremoving soluble impurities from salt is spraying of brine or water over a layer of salt - on a heap, on a screen, on a wire mesh belt or in a screw conveyor.

Answer 2

Explanation:

ANSWER:-

Method 1:-

• This is a process in which we first use filtration and evaporation .
• First, we take the salt and dissolve it in water.
• As salt or common salt completely mixes, after which we can see impurities floating.
• We allow it to settle. This process was Sedimentation.
• After 1 or 2 hour we pour it slowly to separate the constituents .
• Now, heat the water strongly. After that we will get the required salt.

Method 2:-

• This method is quite short, but we need more materials .
• We need filter paper, funnel , holder and a glass .
• First, we will set the filter paper in funnel and place it above the glass via holder.
• After that, we pour the mixture (after the salt is dissolved)
• we get the salt solution.
• Now we will evaporate and get back our salt. This all must be done under adult supervision.
