In a lab, the teacher asked the students to prepare 2 molar solution of oxalic acid (molar mass = 63). As a science student, help them to prepare the above solution.

The teacher asked the student to prepare 200 ml 0.1 M AgNO_3 solution. If a copper stirrer is used for stirring the solution, will you observe any changes inside the beaker. Expalin why.

Calculate the molarity of a solution containing 2.8g of KOH per litre (molar mass of KOH = 56).

In the lab three students were asked to prepare a colloidal solution. Student A .: Added starch powder into hot water. Student B : Added a small amount of ferric chlorideInto freshly prepared ferric hydroxide. Student C : Added soap In to water.Which type of colloid was prepared by student A, lyophoblc sol or lyophillcsol ?
