WebbYield of potash alum/Mohr’s salt is _____g. Precautions (a) Cool the solution slowly to get good crystals. Avoid rapid cooling. (b) Do not disturb the solution while cooling. (c) Avoid prolonged heating while preparing crystals of ferrous ammonium sulphate, as it may oxidise ferrous ions to ferric ions and change the stoichiometry of the ... Webb8 apr. 2024 · Potassium aluminum sulfate's crystal shape is isometric. In other words, this alum likes to make octahedrons. (Think two pyramids fused at their bases.) If you look at my slideshow, you will see very few octahedrons. source The catch is that crystals can only grow in their preferred crystal shape if they aren't squished. WebbShape of the crystals = ……… Note: The crystals of potash alum are octahedral in shape. Precautions 1. Cool the solution slowly to get good crystals. 2.
