Mar 30, 2023
Ntshiab hydrogen peroxide yog lub teeb xiav viscous kua nrog lub melting point ntawm − 0.43 degree C (31.23 degree F) thiab lub boiling point ntawm 150.2 degree C (302.4 degree F). Cov khoom ntom ntom ntom ntom ntom ntom nti ntawm lub chaw khov yog 1.71 g / cm3, thiab qhov ntom nqi txo nrog nce kub. Nws lub koom haum degree siab dua H2O, yog li nws cov dielectric coefficient thiab boiling point yog siab tshaj dej. Ntshiab hydrogen peroxide yog qhov ruaj khov, thiab thaum cua sov mus rau 153 ° C (307 ° F), nws ua rau tawg mus rau hauv dej thiab oxygen.
Hydrogen peroxide tuaj yeem ua rau miscible nrog dej hauv txhua qhov sib piv, thiab cov tshuaj tsis muaj zog acidic vim nws muaj peev xwm ua kom tsis muaj zog ionization.
H2O2 ↔ H plus HO2- Ka1=2.4 × 10-12
HO2- ↔ H+ plus O22- Ka2≈10-25
Cov khoom ntawm cov tshuaj tiv thaiv ntawm hydrogen peroxide nrog ntau tshaj sodium hydroxide yog Na2O2 thiab H2O. Thaum reacting nrog barium hydroxide, cov khoom yog barium peroxide.
