Describe a procedure to separate a mixture of sugar, black pepper, and pebbles.
Answer (3)
Pass the mixture through a screen to allow the salt and pepper to pass through but traps the pebbles. Mix the salt and pepper with water to dissolve the salt and filter it to get the pepper.
Answer : The procedure to separate the mixture of sugar, black pepper and pebbles would require physical methods.
First step is to pass the mixture through a grid that traps the pebbles in it and allows the passage of black pepper and sugar from it or alternatively, physically hand-picking up the pebbles can also be done.
Next step is to add water to the mixture to the sugar and black pepper, stir this solution until all the sugar dissolves in the water. Then pass this solution from a filter paper and collect the filtrate in a beaker.
The residue would contain the black pepper on it, it can be dried after separation.
To obtain the sugar which is dissolved in water, one can evaporate the water in it and get the sugar at the bottom of the beaker.
To separate a mixture of sugar, black pepper, and pebbles, first remove the pebbles, then dissolve the sugar in water, filter the mixture to separate the black pepper, and finally evaporate the water to obtain sugar. This method utilizes differences in solubility and size to achieve separation. The process includes physical and thermal steps for effective separation.
