Hi
Eksperimentelt Kjemikalier/lsninger Kininsulfat dihydrat ((C20H24N2O2)2H2SO42H2O)[()Qu inine sulphate dihydrate......] Svovelsyre (H2SO4)1M(9wt%) [Svovelsyre 95%...] Tonic Water/Tonic Water Zero: Kininkonsentrasjonen er ca. 70mg/L, merke/produsent noteres p lab Prosedyre I dette fors ket benyttes mikropipetter. Enkelte av lsningene lager du sammen med labpartneren din - hvilke fremgr av beskrivelsen Stamlsning ca. 1000mg kinin/L - denne lager du sammen med labpartneren din: 1. Skyll en 100mL mlekolbe med destillert vann. Fyll kolben noe mindre enn halvfull med destillert vann og tilsett 3mL1M svovelsyre (ikke bruk mikropipette). 2. Vei inn kininsulfat dihydrat [(C20H24N2O2)2H2SO42H2O] nyaktig p en analysevekt og overfr stoffet kvantitativt til kolben. 3. Ls alt stoffet og fortynn deretter til merket med destillert vann. Blindprve, kalibreringslsninger og prvelsninger: 4. Merk mlekolbene ( 6 stk. 100mL og 3 stk. 25mL ) og skyll alle med destillert vann. Det skal lages figende lsninger: a. En blindprve (100 mL) - denne kan du lage sammen med labpartneren din b. Fem kalibreringslsninger (100mL) c. Tre paralleller med prvelsning av Tonic Water og Tonic Water Zero (25mL) i need to classify HSO4 1M (9 wt%). What does it mean and specially 9 wt%? on ecoonline only 95% H2SO4 is classified.
and how do I calculate mass of quinine sulphate dihydrate ((C20H24N2O2)H2SO42H20)?
the mass of quinine sulphate dihydrate that must be weighed in to make the stock solution (see sections 1 - 3) NB! Note that the concentration in the stock solution is in mg quinine/L (and not mg quinine sulfate dihydrate/L). Note at the same time the chemical formula for quinine sulfate dihydrate (see Chemicals/Solutions) and for quinine (see Theory, figure 3)
