Can you dissolve .35 moles of Potassium Permanganate (KMnO4) into 500 mL of water?
The solubility of potassium permanganate in water at 2o 0C is 64 g/l (or 32 g/0,5 L).The molar mass of KMnO4 is 158,034 g and 0,35 moles KMnO4 is equal to 55,312 g.So it is not possible to dissolve o,35 moles KMnO4 in 0,5 L.
How can you distiguish between hexene and hexane?
These compounds may be distinguish very easily hexene is an unsaturated compound and undergoes addition reactions with Bromine water(Red) and aqueous solution of KMnO4(Violet), the decolorization of these reagents confirm the presence of hexene while benzene is an aromatic compound and does not react with Br2 and KMnO4 solution.
How the you use the percent composition in every day?
You can use percent composition to see how much much flour contributes to the mass of an overall cake. You can see how much kool aid powder is in a given amount of kool aid drink, in percentage. Percentage composition can be used for virtually anything that has a mixture of things. So you don't always have to think percentage composition refers to chemical compounds, such as H2O or KMnO4.
What is the reaction of KmNO4 with formaldehyde?
The formula of formaldehyde is CH2O. The products formed are sodium formate (HCOONa) and methanol (CH3OH). The stoichiometric equation is then X CH2O + Y NaOH --> A HCOONa + B CH3OH. Balancing the equation makes the coefficients 2 CH2O + NaOH --> HCOONa + CH3OH.
Which compounds are used in laboratory prepration of oxygen gas?
Lab preparation of oxygenTo prepare oxygen; you would need the following apparatus:1.Test tubes2.Manganese (IV) dioxide (MnO2)3. Hydrogen peroxide (it must be fresh and kept away from light)(H2O2)4. Wooden splinter (only needed if you are going to check how oxygen helps in combustion).5.Candle and matchsticks.Method:1.First, take the test tube and put a little bit of MnO2 (Manganese dioxide)2. At this time, you will need a friend's or someone else's help (only if you are requiring it to check how oxygen helps in combustion). First, tell your friend to light the candle and to ignite the splinter using the candle. At that time, take a small amount of hydrogen peroxide in a beaker or test tube. Then, tell him/her to to bring the wooden splinter close to the test tube. As soon as he/she brings it, put a little bit of hydrogen peroxide (not more than 1ml). You should see the reaction forming a gas, which looks like smoke. This gas is Oxygen.3. What happens to the splinter when you bring it close to Oxygen? Of course!The splinter burns more brightly and intensely.4. Should you want to only collect Oxygen, you need not do the second part of the second step.Precautions:1. Do not drop the test tubes.2. Always wear gloves while performing chemical experiments.3. Always wear lab coats while doing the same.4. Do NOT eat or manganese oxide or rub them on your eyes. Serious problems may occur, which even might result in blindness or death.5. Do NOT put warmed hydrogen peroxide on your skin. You might get a boil.6. Never stand too close to the test tube.7. If you are untrained, always seek for someone who is better at you in performing lab experiments, or anyone who already has done the lab preparation of Oxygen.8. Keep H2O2 and MnO2 away from children.9. If Oxygen gets into your eyes and you get an irritation, wash your eyes with cold water immediately.I am sure this helped! Good luck in becoming a RAD scientist!
What is molarity of a solution that contains 0.798 g KMnO4 in 50.0 mL solution?
The molar mass of KMnO4 is 158,3415 g.The molarity of this solution is 0,1 M.
What mass of KMnO4 is required to prepare 3.00 liters of a 0.05253 M solution of KMnO4?
24 g
Why does alkene reacts kmno4?
KMnO4 will react with compounds having unsaturation (double bond or triple bond). Since alkenes have double bond, it will react with KMnO4 and decolourize dilute KMnO4 solution.
What is KNMO4 solution?
There is no such solution.You probably mean KMnO4 which is Potassium Permanganate solution.
How many moles of KMnO4 are present in 75.0 mL of a 0.0950 M solution?
Molarity = moles of solute/Liters of solution ( 75.0 ml = 0.075 Liters ) Algebraically manipulate, moles of solute = Liters of solution * Molarity Moles KMnO4 = (0.075 Liters)(0.0950 M) = 7.13 X 10 -3 moles KMnO4 ------------------------------------
Which solution may be used to disinfect water?
a dilute aqueous solution of KMnO4 may be used.
You have .2 n kmno4 which you have to dilute it to 0.05n kmno4 how can you dilute that?
4 x. Take 25ml of 0.2 M solution and dilute to 100ml.
What happen when ethanol is heated with alkaline kmno4 solution?
When ethanol is added to alkaline KMno4 solution, the ethanol gets oxidised to ethanoic acid due to nascent oxygen. KMno4 is an oxidising agent. thus when we first add alkaline Kmno4 to ethanol, the pink colour of the Kmno4 vanishes, as it is being used up for the oxidation process. however. when all of the ethanol has been oxidised into ethanoic acid, and we keep adding Kmno4, the colour returns, as there is no more ethanol left to oxidise.
Which meniscus is to be seen in the burette containing kmno4 solution and why?
upper meniscus...
What is KnMO4?
There is no such solution.You probably mean KMnO4 which is Potassium Permanganate solution.
Does ethyne decolourize KMnO4 solution?
Yes it does. This is a general test for unsaturation.
Is KMnO4 soluble or not soluble is cyclohexane?
No the purple solid KMnO4 is only very slightly soluble in the organic liquid cyclohexane.
