Which pieces of apparatus are needed to obtain solid lead iodide from 20cm3 of aqueous lead nitrate?
To obtain solid lead iodide from 20cm3 of aqueous lead nitrate, you would need a source of iodide ions (e.g., potassium iodide), a filtration apparatus to separate the solid lead iodide from the solution, a beaker or container to collect the solid, and a drying oven or desiccator to dry the collected solid. Optional equipment includes a stirring rod and a hot plate to facilitate the reaction.

What acid is needed to produce ammonium nitrate?
Nitric acid is required to produce ammonium nitrate. Ammonium nitrate is formed by reacting nitric acid with ammonia.
What is the formula of the ionic compound of calcium iodide?
The formula of calcium iodide is CaI2. This is because calcium is a group 2 element with a 2+ charge, while iodide is a group 17 element with a 1- charge. Therefore, to balance the charges, two iodide ions are needed for each calcium ion.
How many grams of lithium nitrate will be needed to make 250 grams of lithium sulfate assuming that you have an adequate amount of lead sulfate to do the reaction?
To determine the number of grams of lithium nitrate needed to make 250 grams of lithium sulfate, you need to calculate the molar mass of lithium sulfate and lithium nitrate, then use stoichiometry to find the ratio of lithium nitrate to lithium sulfate. Finally, apply this ratio to find the mass of lithium nitrate needed for the reaction. Lead sulfate is not involved in this calculation as it is not part of the reaction between lithium nitrate and lithium sulfate.
Why double amount of potassium iodide is required for dissolving iodine?
It sounds like you're describing Lugol's iodine. It's not technically "required," it's just that's what the recipe is. Actually, in Lugol's iodine, KI is needed to improve the dissolution of iodine in water.
What ion did needed by the unhealthy place to get The right levels of nitrogen?
The unhealthy plant likely needed nitrate ions (NO3-) to get the right levels of nitrogen. Nitrate is a common form of nitrogen that plants can absorb and use for growth and development.
How many grams of potassium iodide will produce 750 grams of silver iodide when there is an excess of silver nitrate?
530,3 g potassium iodide are needed.
Why do we rinse the leaf I water?
The leaf was rinsed in water to rehydrate it. Iodine solution is an aqueous solution of iodine/potassium iodine - potassium tri-iodide; water is needed inside the leaf to enable penetration by diffusion.
What mineral is needed for protein metabolism?
Nitrate is needed for protein metabolism.

Add an excess of potassium iodide to copper sulphate solution how much is excess?
The amount of excess potassium iodide depends on the stoichiometry of the reaction between potassium iodide and copper sulfate. One equivalent of potassium iodide is needed to react with one equivalent of copper sulfate. Excess potassium iodide would be any amount added beyond this stoichiometric ratio.
