Ammonium thiosulfate is a colorless, transparent liquid or white crystal. The relative density of crystals is 1.679. It is very soluble in water and has a solubility of 103.3g/100ml water at 100 °C. Ammonium thiosulfate is insoluble in alcohol and ether, but slightly soluble in acetone. When the ammonium thiosulfate is heated to 150 ° C, it decomposes to form ammonium sulfite, sulfur, ammonia, hydrogen sulfide and water. Ammonium thiosulfate is very unstable in air and stable in ammonia.
Thiosulfate ammonium ແມ່ນເປັນ crystal ທີ່ບໍ່ມີສີ, ມີຄວາມໂປ່ງໃສຫຼືເປັນສີຂາວ. ຄວາມຫນາແຫນ້ນຂອງກາຊວນແມ່ນ 1,679. ມັນມີນ້ໍາຫຼາຍໃນນ້ໍາແລະມີຄວາມສະອາດຂອງນ້ໍາ 103.3g / 100ml ໃນ 100 ° C. Thiosulfate ammonium ແມ່ນ insoluble ໃນເຫຼົ້າແລະ ether, ແຕ່ເລັກຫນ້ອຍໃນ soluble acetone. ໃນເວລາທີ່ thiosulfate ammonium ໄດ້ຖືກໃຫ້ຄວາມຮ້ອນ 150 ° C, ມັນ decomposes ເພື່ອປະກອບເປັນ ammonium sulfite, ຊູນຟູຣີນ, ammonia, hydrogen sulfide ແລະນ້ໍາ. thiosulfate ammonium ແມ່ນບໍ່ສະຖຽນລະພາບຫຼາຍໃນອາກາດແລະມີຄວາມຫມັ້ນຄົງໃນອາໂມເນຍ.
