A small sample of potassium sulfate could be prepared by (carefully) mixing a small amount of sulfuric acid with a small amount of potassium hydroxide and then evaporating the water off to leave the potassium sulfate. The two reactants should be measured carefully so that complete neutralization occurs without any remaing reactants, but this is a relatively easy way to make up the required compound. The acid and base react to form the salt and water in the classic manner.

How naphthalene and potassium sulphate mixture separated from each other?
Naphthalene and potassium sulfate can be separated through a process called recrystallization. Since naphthalene is soluble in organic solvents like ethanol or acetone but potassium sulfate is soluble in water, one can dissolve the mixture in a suitable solvent. Afterward, the solution can be filtered to remove the insoluble potassium sulfate, and naphthalene can be recovered by evaporating the solvent. Alternatively, differences in melting points could also be exploited, as naphthalene has a melting point of about 80°C, while potassium sulfate remains solid at that temperature.
Is potassium sulphate a base or acidic?
Potassium sulfate is neither base nor acid - it is a salt. You could get it by mixing something like potassium hydroxide (a base) with sulfuric acid and allowing the neutralization reaction to occur. Since it is actually often produce by reacting potassium chloride with sulfuric acid to get potassium sulfate and HCl (aka hydrogen chloride, aka hydrochloric acid when dissolved in water) you might expect it to be contaminated with some residual acid.
What is the formula of the compound containing potassium ions sulfur ions and oxygen ions?
Unless someone knows better I don't think such a compound could exist. All these elements are pretty electronegative and probably would not be able to combine together.
What is the word equation of potassium hydroxide and sulphuric acid?
If is K2O (potassium oxide) it would be: K2O+H2SO4=K2SO4+H2O It could also form potassium bisulfate: K2O + 2 H2SO4 = 2 KHSO4 + H2O But I'm not sure if you are referring to potassium peroxide (K2O2) or superoxide (KO2)
How could a sample of gas be collected at the anode during-electrolysis of copper sulfate?
A sample of gas collected at the anode during the electrolysis of copper sulfate would likely be oxygen gas (O2) due to the oxidation of water at the anode. This would be because during this process, water is split into oxygen gas and protons, with the oxygen gas being produced at the anode.
How many years old is argon -40?
Argon-40 is a stable isotope with a half-life of 1.25 billion years. To determine its age, scientists measure the ratio of argon-40 to potassium-40 in a sample, which allows them to calculate the age of the sample based on the decay of potassium-40 to argon-40.
How is cuprous iodide formed from potassium iodide?
Cuprous iodide can be formed from potassium iodide by mixing a solution of copper(II) sulfate with potassium iodide. The reaction between the two compounds results in the precipitation of cuprous iodide, which is a solid compound. This solid can then be filtered and dried to obtain cuprous iodide.
What tests could be used to verify the composition of alum?
Find the melting point of the compound and compare it to the published value for alum. You could also analyze by water of hydration by burning the compound until all of the water of hydration is burned off. Then find the mass of the dry crystals and compare it to the correct value.
How do you think you could select a random sample of your classmates?
It depends on the what the sample is for, but at least get both girls and boys in the sample.
What would calcium nitrate react with?
francium ceasium Potassium Sodium Lithium These metals could react with calcium nitrate in a displacement reaction as they are more reactive. e.g. pottasium + calcium nitrate -> calcium + pottasium nitrate.
What is the sample size for a population of 60010?
well a sample size can be any size depending on the requirements. A sample size could be 10 people of that entire population or it could be 1000 people.
Is potassium nitrogen oxide having the formula KNO3?
Potassium (K) does not readily combine with potassium nitrate (KNO3).
