ACTIVITY Applying the formula Sörensen and properties of the product logarithm log = log + log and potency log log in, find the pH of a shampoo that has 8 .10 mol / L ion H and explain if you would use this shampoo to smooth your hair. You've probably found "pH" on labels of shampoo, soaps, cosmetic creams, medicines, mineral water, fruit juices, etc.. Would you buy a product whose announcement indicated the neutral pH as a benefit to your skin or your hair? The human body is an aqueous system where the control of the concentration of ions H is very important. The chemical reactions in our body are very sensitive to changes in pH. Our body must maintain blood pH between 7.35 and 7.45, downward changes (acidosis - causes disorientation, coma and even mor- te) or upward (alkalosis - causes cramps and convulsions) may impair the functioning of vital organs. For example, when a person goes to high altitudes, such as in Bolivia, alkalosis may occur, or decrease the concentration of CO in the body and increases the pH. The human body has several systems to prevent pH changes. Buffer systems are known which combine immediately with either acid or base avoiding sudden changes in pH. For example, proteins and hemoglobin- bina blood act as buffer systems, as they have in their molecules acid group -COOH and basic group -NH Did you know that there are painkillers and antacids buffered to prevent excessive acidity of the stomach? Soft drinks are also buffered systems. And if you have an aquarium, uncompensated, you use a control system for pH buffer.

AKTIVNOST Primjenom formula Sorensen i svojstva proizvoda logari prijaviti = log + log i potenciju log . prijaviti, naći pH šampon koji ima 8 0,10 mol / l ion H i objasniti ako bi koristili ovu šampon za glatke kose. Vjerojatno ste pronašli "pH" na etiketi šampona, sapuna, kozmetičkih kreme, lijekovi, mineralna voda, voćni sokovi, itd.. Želite li kupiti proizvod čija Najava naznačeno neutralni pH kao naknada za vašu kožu ili kosu? Ljudsko tijelo je vodena sustav u kojem je kontrola koncentracije iona H je vrlo važno. Kemijske reakcije u našem tijelu su vrlo osjetljive na promjene pH. Naše tijelo treba održavati pH krvi između 7,35 i 7,45, dolje promjene (acidoza - uzroci dezorijentiranost, koma, pa čak i mor- TE) ili gore (alkalozu - uzroci grčevi i grčevi) mogu utjecati na rad vitalnih organa. Na primjer, kada osoba ide na visokim nadmorskim visinama, kao što su se u Boliviji, alkalozu može dogoditi, ili smanjiti koncentraciju CO u tijelu i povećava pH. Ljudsko tijelo ima nekoliko sustava kako bi se spriječilo pH promjene. Buffer sustavi su poznati koje kombiniraju odmah bilo kiselina ili baza izbjegavaju nagle promjene u pH. Na primjer, proteina i hemoglobin- Bina krvi djeluje kao tampon sustava, kao što su oni u svojoj skupini molekula kiseline -COOH i osnovnih skupina NH- Jeste li znali da postoje lijekovi protiv bolova i antacidi puferirana spriječiti prekomjernu kiselost u želucu? Bezalkoholna pića su također buffered sustavi. A ako imate akvarij, neplaćeni, koristite upravljački sustav za pH buffer.
