Volumetrik tahlil nima?

Volumetrik tahlil - bu noma'lum birikmaning miqdorini uning hajmidan foydalanib o'lchash mumkin bo'lgan miqdoriy tahlilning bir turi. Biz bu maqsadda titrlashdan foydalanishimiz mumkin. Shuning uchun biz bu tahlilni "titrimetrik tahlil" deb ataymiz. Titrlashda biz namunada mavjud bo'lgan noma'lum birikma hajmini aniqlash uchun ikkinchi eritma yoki reagentdan foydalanamiz. Noma'lum hajmni aniqlab, biz bu birikmaning namunadagi konsentratsiyasini aniqlashimiz mumkin.
