Ke\u010f sa hovor\u00ed o vren\u00ed s\u00f3dy bikarb\u00f3ny<\/strong> (hydrog\u00e9nuhli\u010ditan sodn\u00fd), nejde len o bublinky. Pri zahriat\u00ed nad $60\\text{\u2013}80\\text{\u00b0C}$ (alebo pri dlhom varen\u00ed) doch\u00e1dza k chemick\u00e9mu rozkladu:<\/p>\n\n\n\n

$$2NaHCO_3 \\rightarrow Na_2CO_3 + H_2O + CO_2$$<\/p>\n\n\n\n

Z oby\u010dajnej s\u00f3dy bikarb\u00f3ny sa st\u00e1va uhli\u010ditan sodn\u00fd<\/strong> (zn\u00e1my ako pracia s\u00f3da). A pr\u00e1ve v tom spo\u010d\u00edva t\u00e1 \u201eobrovsk\u00e1 hodnota\u201c, ktor\u00fa spom\u00edna\u0161.<\/p>\n\n\n\n

\n\n\n\n

Pre\u010do by ste to mali robi\u0165? (Praktick\u00e9 vyu\u017eitie)<\/h2>\n\n\n\n

1. Extr\u00e9mna sila pri \u010disten\u00ed prip\u00e1len\u00edn<\/h3>\n\n\n\n

Ak m\u00e1te hrniec s prip\u00e1len\u00fdm dnom, kde ni\u010d nepom\u00e1ha:<\/p>\n\n\n\n

    \n
  • Nalejte vodu, pridajte 2 ly\u017eice s\u00f3dy a dajte vari\u0165 na 10-15 min\u00fat<\/strong>.<\/li>\n\n\n\n
  • Proces varenia zmen\u00ed pH vody na ove\u013ea z\u00e1saditej\u0161ie. Prip\u00e1lenina sa doslova \u201eodlep\u00ed\u201c od dna bez drhnutia.<\/li>\n<\/ul>\n\n\n\n

    2. Dom\u00e1ca v\u00fdroba pracieho g\u00e9lu<\/h3>\n\n\n\n

    Ak vyvar\u00edte s\u00f3du a nech\u00e1te vodu odpari\u0165 (alebo upe\u010diete such\u00fa s\u00f3du v r\u00fare), z\u00edskate silnej\u0161iu alkalick\u00fa l\u00e1tku, ktor\u00e1 je z\u00e1kladom pre ekologick\u00e9 pranie. Rozpust\u00ed mastnotu ove\u013ea efekt\u00edvnej\u0161ie ne\u017e be\u017en\u00e1 s\u00f3da z vrecka.<\/p>\n\n\n\n

    3. Odpchatie odtoku bez agres\u00edvnej ch\u00e9mie<\/h3>\n\n\n\n

    Namiesto sypania pr\u00e1\u0161ku sk\u00faste do odtoku nalia\u0165 vriaci roztok vody a s\u00f3dy<\/strong>. Teplo ur\u00fdch\u013euje reakciu s usaden\u00fdm tukom (zmen\u00ed ho na druh mydla), \u010d\u00edm sa potrubie vy\u010dist\u00ed \u0161etrnej\u0161ie ne\u017e l\u00fahom.<\/p>\n\n\n\n

    4. Pr\u00edprava “Precl\u00edkov” (Laugengeb\u00e4ck)<\/h3>\n\n\n\n

    Toto je tajomstvo pek\u00e1rov! Ak chcete, aby mali dom\u00e1ce pracl\u00edky t\u00fa kr\u00e1snu tmavohned\u00fa leskl\u00fa k\u00f4rku:<\/p>\n\n\n\n

      \n
    • Pripravuje sa k\u00fape\u013e z vriacej vody a s\u00f3dy, v ktorom sa cesto pred pe\u010den\u00edm kr\u00e1tko povar\u00ed. Varen\u00edm sa s\u00f3da zmen\u00ed na silnej\u0161iu z\u00e1sadu, ktor\u00e1 pri pe\u010den\u00ed sp\u00f4sob\u00ed dokonal\u00fa Maillardovu reakciu<\/em>.<\/li>\n<\/ul>\n\n\n\n
      \n\n\n\n

      Na \u010do si da\u0165 pozor?<\/h2>\n\n\n\n
        \n
      • Hlin\u00edk:<\/strong> Nikdy nevarte s\u00f3du v hlin\u00edkov\u00fdch hrncoch! Vysok\u00e9 pH hlin\u00edk po\u0161kodzuje a hrniec s\u010dernie. Pou\u017e\u00edvajte nerez alebo smalt.<\/li>\n\n\n\n
      • V\u00fdpary:<\/strong> Pri varen\u00ed sa uvo\u013e\u0148uje oxid uhli\u010dit\u00fd ($CO_2$). Nie je to nebezpe\u010dn\u00e9, ale v malej kuchyni je dobr\u00e9 vetra\u0165.<\/li>\n<\/ul>\n\n\n\n
        \n

        M\u00f4j tip:<\/strong> Ak m\u00e1te doma star\u00e9 strieborn\u00e9 pr\u00edbory, vlo\u017ete ich do misky s alobalom a zalejte ich pr\u00e1ve t\u00fdmto vriacim roztokom s\u00f3dy. Za p\u00e1r sek\u00fand bud\u00fa \u017eiari\u0165 ako nov\u00e9 bez jedinej \u0161tipky le\u0161tenia!<\/p>\n<\/blockquote>\n\n\n\n

        Chceli by ste vedie\u0165 presn\u00fd pomer na ten dom\u00e1ci \u010disti\u010d odtokov, alebo v\u00e1s zauj\u00edma, ako presne upiec\u0165 t\u00fa s\u00f3du v r\u00fare na pranie?<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
