The invention discloses a process for producing potassium chloride with a purity above 99 percent. The process comprises the following steps: taking 50 grams of potassium chloride with a purity below98 percent;
So some physicians prescribe as a replacement seasoning potassium chloride (氯化钾), which tastes salty but contains no sodium. Meanwhile, it should also be taken into account that extremely heavy use of potassium unlikely because of its unpleasant taste in large doses―can cause death. Hence, ...
What is the percent composition of potassium sulfite? A certain element consists of two stable isotopes. The first has a mass of 14.0 amu and a percent natural abundance of 99.6%. The second has a mass of 15.0 amu and a percent natural abundance of 0.370%. What is the atomic weight of...

In osmosis, what does "concentration" refer to - is it the concentration of water potential or is it the concentration of solutes? Calculate the volume of potassium hydroxide of 0.15 mol dm ^3 concentration that would need to be added to 100 cm ^3 of potassium dihydrogenphosphate solu...
How many moles of MgS are present in a given mass of 5.6 g? What is the concentration in percent mass/volume of 500 ml water and 4.5 g NaCl when heated? A sample of 70.5 g of potassium phosphate is added to silver nitrate, ...
