摘    要:在强酸与一元弱酸混合酸的各组分酸含量测定中,为更简便,在理论上推导出结果的误差△Ve2/Y2与△pH之间的关系式,从而求出pH大于3.7时第一终点的αA的允许最大值.由此提出混合酸标准溶液的半中和点为第一终点的各组分酸含量测定方法,方法简便、可靠.

关 键 词:酸类,化学,分析,半中和点

Abstract:The relative formula of the error value△Ve2/Vand △ pH was theoreticallydeduced in the determination of each acid content from a mixture of strong and weakmonoacids and the permited maximum aA -of the first terminal point was calculated whenthe pH is over 3.7. From that,the method of determinating each component acid contentof first terminal point was deduced by half neutralization point method of mixed acidstandard solution that was handy and reliable.
Keywords:acids  chemistry   analytical  half neutralization point
