ຄໍາຖາມທີ່ຖາມເລື້ອຍໆ

ຮູບຮ່າງ pH ແມ່ນຫຍັງ?

pH ແມ່ນ ໂລກາຣິຕມ 10 ຖານລົບ ຂອງ ຄວາມເຂັ້ມຂົ້ນຂອງໄຮໂດເຈນ-ໄອໂອນ, pH = -log₁₀[H⁺]. ຄວາມເຂັ້ມຂົ້ນຂອງ 1×10⁻⁷ mol/L ເຮັດໃຫ້ pH neutral ຂອງ7.

pH ແລະ pOH ກ່ຽວຂ້ອງກັນແນວໃດ?

ດັ່ງນັ້ນ, ສານລະລາຍຂອງ pH3ມີ pOH 11, ແລະຄວາມເຂັ້ມຂົ້ນຂອງ hydroxide ແມ່ນ [OH⁻] = 10⁻¹¹ mol / L.

ລະດັບ pH ມີຄວາມໝາຍແນວໃດ?

ຂ້າງລຸ່ມ7ແມ່ນອາຊິດ,7ແມ່ນ neutral, ແລະ ຂ້າງເທິງ7ແມ່ນພື້ນຖານ (alkali). ຂະໜາດປົກກະຕິແລ້ວແມ່ນ 0- 14, ເຖິງວ່າອາຊິດຫຼືພື້ນຖານທີ່ແຂງແຮງສາມາດຕົກຢູ່ນອກມັນໄດ້ເລັກນ້ອຍ. ຕົວຄິດໄລ່ຈັດປະເພດຄ່າຂອງທ່ານເປັນອາຊິດ, neutral ຫຼືພື້ນຖານ.

ເຮັດຫຍັງ pH ຈຶ່ງເປັນລໍກາຣິດມິກ?

ຕົວເລກທີ່ໃຊ້ໃນການວັດແທກແມ່ນຕົວເລກທີ່ໃຊ້ໃນການວັດແທກຄວາມເຂັ້ມແຂງຂອງໄຮໂດເຈນໃນນໍ້າ.

ຂ້ອຍຈະພົບ [H⁺] ຈາກຄ່າ pH ໄດ້ແນວໃດ?

ປ່ຽນຄວາມໝາຍຄືນໃໝ່: [H⁺] = 10^( −pH). pH ຂອງ3ໃຫ້ [H⁺] = 10⁻³ = 0. 001 mol/ L. ເລືອກແບບ "ຈາກຄ່າ pH" ແລະເຄື່ອງຄິດໄລ່ຈະສົ່ງຄືນຄວາມເຂັ້ມແຂງໃຫ້ທ່ານ & # 160; ។

pH ປ່ຽນແປງຕາມອຸນຫະພູມບໍ?

ຖືກ. ຈຸດກາງຂອງ7ແລະກົດ pH + pOH = 14 ຖືຢູ່ທີ່ 25 °C; ເມື່ອອຸນຫະພູມສູງຂຶ້ນ ນ້ຳຈະໄອໂອນຂຶ້ນຫຼາຍ, ສະນັ້ນ pH ກາງຈະຕົກຢູ່ພາຍໃຕ້7ແລະມູນຄ່າລວມຈະຕົກລົງເລັກນ້ອຍ. ເຄື່ອງມືນີ້ໃຊ້ຄ່າມາດຕະຖານ 25 °C.
