What is the symbol for a concentrated acid?
The symbol for a concentrated acid is typically shown as "conc. HX," where "X" represents the specific acid. For example, concentrated sulfuric acid would be written as "conc. H2SO4."
What happen when KBr is heated with conc H2So4 acid?
Balanced equation formed: H2SO4 + 2KBr ==> 2HBr + K2SO4
What is conc sulfuric acid?
Conc sulfuric acid is short for concentrated sulfuric acid, which refers to sulfuric acid that has a high concentration of H2SO4, typically around 95-98%. This form of sulfuric acid is highly corrosive and can cause severe burns upon contact with skin. It is commonly used in industrial processes such as manufacturing chemicals, refining petroleum, and in laboratory settings.
Reaction of potassium astatide with concentrated sulfuric acid?
KAt + H2SO4(conc) = KHSO4 + HAt displacement then .......HAt + .......H2SO4 = At2 + H2S which can be balanced as follows: 2At- = At2 + 2e ] * 4 8e + 8H+ + H2SO4 = H2S + 4H2O overall is 8At- + 8H+ + H2SO4 = H2S + 4H2O + 4At2
What are the properties and uses of conc. H2SO4?
Concentrated sulfuric acid (H2SO4) is a strong mineral acid that is highly corrosive and can cause severe burns. It is commonly used in various industries for purposes such as manufacturing fertilizers, refining petroleum, and in the production of chemicals. Its properties include being a strong dehydrating agent, a powerful oxidizing agent, and a catalyst in various chemical reactions.
Why it is necessary to add conc H2SO4 in conc HNO3 but not vice versa?

Why the conc h2so4 cant be used in preparation oh h2s?
h2so4 being good oxidising agent oxidises the h2s to h2o and free sulphur.so conc h2so4 cant be used in preparation of h2s gas

What do you use nitric acids for in laboratory?
lABORATORY METHOD:Nitric acid can be prepared in he laboratory by the action of the conc. h2so4 on the potassium nitrate

What is the principle of BOD?
when magnesium sulfate and potassium hydroxide is added,magnesium hydroxide is formed and precipitates and conc H2SO4 is added and in presence of oxygen the preciptate turns brown color which can be measured by idoine and starch indicator titrated against sodium thiosulfate
What is acidic dew point?
The dew point of H2SO4 in a flue gas varies according to the concentration of H2SO4 in that flue gas.the more is the conc. the higher will be dew point. Normally it varies b/w 137-160C.
How is the strength of hydrogen peroxide changed?
Water is added to decrease the Conc^ or the water is evaporated of to increase the Conc^
How do you prepare the 1.25 percent H2SO4 solution?
Concentrated H2SO4 is 96 %.( In laboratory ) As density of concentrated H2SO4 is 1.84gm/ml we will need this number as well, and as the atomic mass of H2SO4 is 98.08,as it is dibasic for normality it is 49 hence, Calculation=((96/100)(1000)(1.84))/49=36.04 If H2SO4 concentrated is 36.04 M then for make a 1L solution of 1M H2SO4 (36.04)X (x) = 1X(1) x = 1 X(1) / (36.04) x=0.0277gm/ml of water x = 27.7 mL of 36M H2SO4 per liter Hence for 1N H2SO4 dissolve 27.7ml of it to 1000ml of solvent(Water) that means for 0.1 N H2SO4 2.77 ml of it to 1000mL of solvent.
