\"\"<\/a>Sert suda, sabun kalsiyumla (sert suda nispeten y\u00fcksek olur) reaksiyona girerek “sabun tortusu” olu\u015fturur. Bu y\u00fczden de sert su kullan\u0131m\u0131nda; elleriniz, sa\u00e7lar\u0131n\u0131z veya \u00e7ama\u015f\u0131rlar\u0131n\u0131z olsun, e\u015fyalar\u0131 temizlemek i\u00e7in daha fazla sabun veya deterjan gerekir.<\/p>\n

Bula\u015f\u0131k makinesinde bir s\u00fcr\u00fc bula\u015f\u0131k y\u0131kad\u0131n\u0131z, bardaklar\u0131 \u00e7\u0131kard\u0131n\u0131z ve \u00fczerlerinde lekeler mi fark ettiniz? \u0130\u015fte bu sert su kal\u0131nt\u0131s\u0131d\u0131r ve tehlikeli de\u011fildir ama g\u00f6ze ho\u015f g\u00f6r\u00fcnmez. Pek \u00e7ok end\u00fcstriyel ve evsel su kullan\u0131c\u0131s\u0131, sular\u0131n\u0131n sertli\u011finden endi\u015fe duymaktad\u0131r. Ev tipi su \u0131s\u0131t\u0131c\u0131s\u0131nda oldu\u011fu gibi sert su \u0131s\u0131t\u0131ld\u0131\u011f\u0131nda, \u0131s\u0131t\u0131c\u0131da kat\u0131 kalsiyum karbonat birikintileri olu\u015fabilir. Bu durum ekipman\u0131n \u00f6mr\u00fcn\u00fc k\u0131saltabilir, suyu \u0131s\u0131tma maliyetlerini art\u0131rabilir, elektrikli su \u0131s\u0131t\u0131c\u0131lar\u0131n\u0131n verimini d\u00fc\u015f\u00fcrebilir ve borular\u0131 t\u0131kayabilir. Elbette evinizdeki kahve makinenizde de mineral birikimi meydana gelecektir. \u00a0Baz\u0131 insanlar tencerelerinden ara s\u0131ra sirke (bir asit) ge\u00e7irirler. Sirkenin asitli\u011fi, mineral partik\u00fcllerini y\u00fckl\u00fc hale getirerek \u00e7\u00f6z\u00fcnmesine yard\u0131mc\u0131 olur. Bu yeni y\u00fckl\u00fc par\u00e7ac\u0131klar sudaki pozitif ve negatif y\u00fcklere \u00e7ekilir ve kolayca y\u0131kanabilir.\u00a0Sularda iki tip sertlik olabilir; ge\u00e7ici ve kal\u0131c\u0131 sertlik. Ge\u00e7ici sertli\u011fe sahip olan sular\u0131 kaynat\u0131rsak sertli\u011fini yumu\u015fatabiliriz fakat kal\u0131c\u0131 sertli\u011fi bu \u015fekilde gidermek m\u00fcmk\u00fcn de\u011fildir ve kimyasal i\u015flem gerektirir. Ge\u00e7ici sertli\u011fe sebep olan kalsiyum bikarbonat ve magnezyum bikarbonat, su kaynat\u0131ld\u0131\u011f\u0131 zaman kalsiyum ve magnezyum karbonat bile\u015fikleri halinde \u00e7\u00f6ker. Kal\u0131c\u0131 sertlikte ise kaynama ile \u00e7\u00f6kt\u00fcr\u00fclemeyecek kalsiyum ve magnezyum s\u00fclfat bile\u015fikleri s\u00f6z konusudur. \u00a0Asl\u0131nda stronsiyum, demir ve mangan iyonlar\u0131 da sertlik olu\u015fturur fakat bu iyonlar do\u011fal sularda \u00e7ok az bulunduklar\u0131ndan sertli\u011fe fazla katk\u0131lar\u0131 olmaz. \u00a0Sular\u0131n sertlik s\u0131n\u0131fland\u0131r\u0131lmas\u0131 i\u00e7in genel kurallar \u015funlard\u0131r: 0 ila 60 mg\/L (litre ba\u015f\u0131na miligram) kalsiyum karbonat i\u00e7eriyorsa yumu\u015fak olarak s\u0131n\u0131fland\u0131r\u0131l\u0131r; 61 ila 120 mg\/L ise orta derecede sert; 121-180 mg \/L ise sert; ve 180 mg \/ L’ den fazla ise serttir.<\/p>\n
