HCl 20BE txhais tau tias 31.75% concentrated HCl los ntawm huab hwm coj. Qhov ntawd txhais tau tias 100 grams ntawm qhov no muriatic acid muaj 31.75 grams HCl. Rau 1000 ml ntawm kev daws, qhov hnyav yog 1149.3 g, ntawm uas 31.75% yog HCl: 364.9 g. Hauv 364.9g ntawm HCl koj muaj 12.18 moles (364.9/36.46), uas txhais tau tias HCl nyob ib puag ncig 10 M.

Tsis tas li, dab tsi yog qhov molarity ntawm cov kua qaub?

Dilutions los ua 1 Molar Solution

Cov concentrated Reagents	Ceev	Molarity (M)
Hydrochloric acid 36%	1.18	11.65
Hydrochloric acid 32%	1.16	10.2
Hydrofluoric acid 40%	1.13	22.6
Nitric acid 70%	1.42	15.8

Tsis tas li ntawd, qhov molarity ntawm 37% HCL yog dab tsi? Yog li, fuming/concentrated HLW 37 % yog 12 molar (= M = mol/L).

Hais txog qhov no, puas yog cov kua qaub muriatic thiab hydrochloric acid tib yam?

A. Katherine, lawv feem ntau yog cov tib yam -- tua neeg yog lub npe nrov rau kev lag luam, lossis tsawg dua ntshiab, qib ntawm hydrochloric acid . Kho ob qho tib si nrog kev saib xyuas.

Yuav ua li cas txaus ntshai yog muriatic acid?

Tsis muaj xim rau daj me ntsis hauv qhov tsos, muriatic acid tuaj yeem txheeb xyuas los ntawm nws qhov khaus thiab tsw ntxhiab. Ua phem Cov teebmeem tau ntsib los ntawm ntau txoj hauv kev ntawm kev raug rau muriatic kua qaub , suav nrog nqus pa, nqus dej, thiab tawv nqaij lossis qhov muag. Nqis los yog nqus tau muriatic kua qaub tej zaum yuav tuag taus.
