Cov tshuaj txhuam hniav thiab tshuaj tiv thaiv kab mob yog cov piv txwv zoo ntawm cov khoom lag luam thaum cov khoom noj xws li kua txiv kab ntxwv lossis txiv kab ntxwv yog cov kua qaub heev

  1. Qhov ntsuas pH. Qhov ntsuas pH khiav ntawm 1 txog 14 thiab qhia txog qhov ntau ntawm acids thiab bases los ntawm sab saum toj mus rau hauv qab.
  2. Tshuaj txhuam hniav thiab pH.
  3. pH ntawm cov khoom noj khoom haus.
  4. Acid Neutralizing Tshuaj.
  5. Cov khoom siv ntxuav.

Ib yam li ntawd, peb siv cov kua qaub li cas hauv lub neej txhua hnub?

Ib txwm, txhua hnub acids xws li vinegar, muriatic acid (ntxuav cov vuas thiab pob zeb - aka hydrochloric acid), tartaric acid ( siv hauv ci), ascorbic acid (vitamin C), thiab salicylic acid (exfoliant thiab precursor rau aspirin).

Tsis tas li ntawd, cov kua qaub thiab cov hauv paus cuam tshuam li cas rau peb lub neej niaj hnub piav nrog piv txwv? Acids thiab bases cuam tshuam rau lub neej txhua hnub vim tias lawv ua lub luag haujlwm hauv ntau qhov kev cuam tshuam, los ntawm kev zom zaub mov mus rau ntxuav xab npum los ntawm phab ntsa da dej. Cov kua qaub muaj pH tsawg dua 7.0, thaum hauv paus muaj pH ntau dua 7.0. Cov zaub mov qaub saj li ntawd vim yog lawv acidity.

Raws li txoj cai, peb siv cov hauv paus hauv lub neej txhua hnub li cas?

Nov yog 10 lub hauv paus uas feem ntau pom hauv tsev neeg:

  1. Ammonia, tshuaj chiv, tshuaj ntxuav tes
  2. Sodium hydroxide, NaOH (tus neeg saib xyuas, ntawv, pH regulator)
  3. Sodium carbonate, (daim ntawv, iav, tshuaj ntxuav tes, tshuaj txhuam hniav)
  4. Sodium bicarbonate, (baking soda, tua hluav taws, tshuaj txhuam hniav)

Dab tsi yog kev siv cov kua qaub thiab cov hauv paus?

Kev Siv Cov Acids thiab Bases

  • Vinegar: Feem ntau siv hauv chav ua noj, nws suav nrog 3-6% acetic acid.
  • Kev Siv Hluav Taws Xob: Nitric acid thiab sulfuric acid yog ob qho tib si siv hauv chiv, dyes, xim thiab tawg.
  • Roj teeb: Sulfuric acid yog siv rau hauv cov roj teeb uas khiav hauv tsheb thiab teeb nyem rau npe rau ob peb tug.
