Potassium hydroxide exists as a white solid powder, but is highly soluble in alcohols like ethanol. Ethanolic potassium hydroxide is highly acidic in nature. It is highly corrosive when handled. It is an effective conductor of heat, and highly flammable. It appears as a colorless liquid. Manufac...
the seaweed is soaked in alkali solutions such as potassium hydroxide. The heating is to separate the carrageenan from seaweed. Cellulose will then be mechanically removed by centrifugation and filtration. The remaining solution is evaporated to shed off any remaining water. The powdered carrageenan is...
Carbon dioxide is acidic in nature and potassium hydroxide is a strong base. Hence, carbon dioxide reacts with potassium hydroxide to form potassium carbonate and water as 2KOH+CO(2)toK(2)CO(3)+H(2)O Thus, the mass of the U-tube containing KOH increa
In an acid-base neutralization reaction, 20.0 mL of 1.20 M sulfuric acid (H_2SO_4) is added to 25.0 mL of 2.00 M potassium hydroxide (KOH). If the temperature of the solution rises by 13.2^oC, what is the heat of neutralization for sulfuric acid, in kJ/mo ...
A strong base is something like sodium hydroxide or potassium hydroxide which is fully ionic. ... Each mole of sodium hydroxide dissolves to give a mole of hydroxide ions in solution. Some strong bases like calcium hydroxide aren't very soluble in water. Is 6.4 acidic or basic? While 7 is...
A solution of potassium hydroxide is used to absorb carbon evolved during the estimation of carbon in an organic compound. Explain. View Solution Doubtnut is No.1 Study App and Learning App with Instant Video Solutions for NCERT Class 6, Class 7, Class 8, Class 9, Class 10, Class 11 and...
Why is potassium permanganate colored? Why does chloroform, under some conditions, dissolve in a mixture of acidic acid and water? Why is it important to perform the ammonia tests with no other sets of cations in the tray? Why does the funnel must be removed from the burette while titration...
It contains iron, potassium and hydroxide. The interesting thing is that on Earth at least it needs highly acidic water to form. So we’ve got water or had it at one point. And since most planetary scientists believe that water is essential to life, the presence of jarosite means that on...
The neutralizing agent of Cabo 940 can be sodium hydroxide, potassium hydroxide, potassium bicarbonate, borax, amino acids, and polar organic amines such as triethanolamine. 2. The water swelling ability of carbomer mainly depends on the cross-linking density of the polymer...
