The solubility of KNO_3 is 155 g per 100 g of water at 75 ... - Socratic
2016年1月4日 · At this temperature, dissolving less than "38.0 g" of potassium nitrate per "100 g" of water will result in an unsaturated solution. At the "38.0 g" mark, the solution will become saturated. Now, take a look at how the solubility graph for potassium nitrate looks like So, you are starting with "100 g" of saturated solution at 75^@"C".
Lead (II) nitrate reacts with potassium iodide to form lead
2015年12月28日 · Finally, in potassium nitrate, the charges balance in another 1 : 1 ratio, giving a formula of "KNO"_3 . The symbol equation is as follows: "Pb(NO"_3")"_2 + "KI" -> "PbI"_2 + "KNO"_3 The most obvious change we must make, when balancing this equation, is to increase the number of nitrate ions on the right hand side of the equation.
How can I calculate solubility of potassium nitrate? - Socratic
2014年7月28日 · The only way to determine the solubility of potassium nitrate is to do an experiment or interpolate from a solubility graph. Solubility is the mass of a solute that can be dissolved in a given mass of solvent. Solubility varies according to temperature for the same solute and solvent. The solubility graph for potassium nitrate in water is shown below. …
Saturated and Supersaturated Solutions - Chemistry - Socratic
How many more grams of potassium nitrate must be added to make the solution saturated? A solution of potassium chlorate, #KCIO_3#, has 20 grams of the salt dissolved in 100 grams of water at 70 C. Approximately how many more grams of the salt can be added to the solution before reaching the saturation point?
What are the products of Potassium iodide + lead nitrate?
2016年10月20日 · This is a double replacement reaction. Potassium and lead are cations (positively charged ions). Iodide and Nitrate are anions (negatively charged ions). To find the products, you need to swap the anions with another cation and the cation with another anion. So, you have Potassium Iodide and Lead Nitrate. You want to move the 'Nitrate' anion and place it …
