Analiz natijalarini hisoblash
Bu yerda, NNaOH - ishqorning normalligi; VNaOH - ishqorning titrlashga sarflangan hajmi, ml; ЭHА - tekshiriladigan kislota ekvivalentining molyar massasi; Vk - tekshiriladigan eritmaning umumiy hajmi, ml; Va - tekshiriladigan eritma alikvot qismining hajmi, ml.
Olingan natijalar jadvalga kiritiladi.
