运用氧化物酸碱性Z_o标度值和离子极化力两参数,提出一种用于计算无机含氧酸盐生成热的经验公式:—△H_f~o=a(△Z_o)~2+b△(Z~*/R)~2+C,用该式计算了53种含氧酸盐的生成热,计算值与实验值符合得很好。
An empirical formula for calculating the heat of formation of inorganic oxyacid salts is proposed by using the two parameters of oxide acid - basicity Z_o and ionic polarization: - ΔH_f ~ o = a (ΔZ_o) ~ 2 + b △ (Z ~ * / R) ~ 2 + C, the calculated heat of 53 kinds of oxo acid salts are calculated. The calculated values are in good agreement with the experimental data.
