how do you create a 0.2N solution of sodium hydroxide using powdered sodium hydroxide
Simple. 5lt is equal to how many moles just count/calaculate moles then simple multiply with molar/mass fraction i.e moles * give n amont of.watch what
Now the "moles of solute" are a constant. The volume of solution MAY change substantially with increasing or decreasing temperature. In some calculations "molality" is used in preference, which is defined by the quotient Molarity is the concentration of a solution expressed as the number of moles of solute per litre of solution. For example, a 0. To calculate the molarity of a solution, you need to know the number of moles of solute and the total volume of the solution. What is the molarity of a solution prepared by dissolving
The effectiveness of sodium hydroxide NaOH and sodium carbonate Na2CO3 on the impurities removal of saturated salt solution. Increasing the quality of salt can be done through various methods such as washing hydro-extraction , re-crystallization, ion exchange methods and others. In the process of salt quality improvement by re-crystallization method where salt product diluted with water to form saturated solution and re-crystallized through heating process. The quality of the salt produced is influenced by the quality of the dissolved salt and the crystallization mechanism applied. In this research is proposed a concept that before the saturated salt solution is recrystallized added a chemical for removal of the impurities such as magnesium ion Mg , calcium Ca , potassium K and sulfate SO4 is contained in a saturated salt solution. This research aims to study effectiveness of sodium hydroxide and sodium carbonate on the impurities removal of magnesium Mg , calcium Ca , potassium K and sulfate SO4. The results showed that the addition of sodium hydroxide solution can be decreased the impurity ions of magnesium Mg
