Things that change in a Experiment!!!
Given:
Sulfur dioxide and dihydrogen sulfide system
Vapor Pressure of water, H2O = 23 torr
P_SO2 = P_H2S
Temperature of the system = 298 K
Assume: Total pressure of the system is 1 atm = 760 torr
If partial pressure of SO2 is equal to the concentration of H2S, then,
760 = 0.5*PSO2 + 0.5PH2S
760 = PSO2
B. HNO3 because it is copper and can not move the place of hydrogen's atom from the acid
Answer:
Explanation:
An Arrhenius acid is any species that increases the concentration of H+start text, H, end text, start superscript, plus, end superscript in aqueous solution. An Arrhenius base is any species that increases the concentration of OH−start text, O, H, end text, start superscript, minus, end superscript in aqueous solution.
Explanation:
It is known that when pH of a substance is more than 7 then the substance is considered basic in nature. When pH of a substance is less than 7 then the substance is considered acidic in nature.
And, when the pH of a substance is equal to 7 then it is considered neutral in nature.
The pH of given substances are as follows.
Coffee = 5.0
Orange Juice = 3.5
Milk = 6.5
Soda pop = 2.5
Battery acid = 1.0
As battery acid as very low pH therefore, it is highly acidic in nature.
Thus, we can conclude that given acids are arranged in increasing order of acidity as follows.
Milk < Coffee < Orange juice < Soda pop < Battery acid
