Why H2S is acidic but H2O is nutral
Answers
Explanation:
H2S have a pH value of 5(acidic) whereas H2O have pH 7(neutral)
Explanation:
H2S =hydrogen sulphide.
the chemical bond of H2S is
H ----- S ----- H
the valency of hydrogen is 1 and valency of sulphur is 1 .
the element of hydrogen in H2S is 2.
when the both hydrogen needs one electron to complete its shell then sulphur gives one one electron to each then capacity of outermost shell of hydrogen is 5. To complete the octet 8 electron is being needed.the half of the octet is 4, then in sulphur 5 electron is there then it is not half of 8 or to complete octet and also the ph value of H2S is less than 7 there fore H2S is acidic.also when the negative electron is also said to be acidic.
H2O= water
chemical bond of H2O is
H------ O ------- H
the valency of hydrogen is 1 and valency of oxygen is 2.
the element of hydrogen in H2O is 2.
when hydrogen needs one one electron then oxygen gives them the needed electron. after giving them electron 4 electron will remain with it. To complete the octet 8 electron is being needed.4 electrons remain with the oxygen is half
than 8 .Both element hydrogen and oxygen can share there electron with each other. Also the pH value of H2O is 7. Therefore, H2O is neutral and H2S is acidic.
hope so this answer will help you.
