 msgid "There are multiple ways of measuring the pH value of a solution, one of which is to use indicator paper. Indicator paper changes color depending on the pH of the solution applied to it, and by comparing to a chart a fairly accurate measure of the solution's pH can be obtained.  If a more accurate measure is needed, a glass electrode can be used, which works by measuring the conductivity of the solution."
-msgstr ""
+msgstr "Ima mnogo naÄina kako izmjeriti pH-vrijednost otopine. Jedan od njih je koristeÄi indikatorski papir. S obzirom na vrstu, postoje crveni lakmus papir (za luÅŸine, poplavi), plavi lakmus papir (za kiseline, pocrveni), univerzalni indikatorski papir za razliÄita pH-podruÄja (na slici mjeri od 1 do 14). Indikatorski papir mijenja boju ovisno o pH otopine, a usporedbom s ljestvicom boja moÅŸe se pribliÅŸno odrediti pH otopine. Za toÄnija mjerenja koristi se pH-metar sa staklenom elektrodom, koji zapravo mjeri provodnost otopine."

 msgid "Burets are used to titrate liquids.  A buret is filled with a specific volume of a liquid, and placed beneath it is a container such as an Erlenmeyer flask.  By opening the valve on the buret, the liquid in the container will then be titrated.  High-quality burets have a venting mechanism with which they can be very easily refilled with the exact volume for which the buret is calibrated."

Otvaranjem pipca na dnu birete, tekuÄina curi iz birete u posudu, tj. titrira se.Visokokvalitetne birete imaju poseban sustav nadopunjavanja na volumen na koji je bireta kalibrirana."
