Sisältö

  • pH
  • Laimeneminen
  • Konsentraatio
  • Hapot
  • Emäkset

Description

Testaa mm. kahvin, syljen ja saippuan pH ja määrittele, ovatko ne happamia, emäksisiä vai neutraaleja. Visualisoi hydroksidi-ionien ja oksoniumionien suhteellinen määrä liuoksessa. Vaihda lineaarisen ja logaritmisen asteikon välillä. Tutki vaikuttaako tilavuuden muuttaminen tai vedellä laimentaminen pH:n arvoon. Voit myös suunnitella oman nesteen!

Esimerkkejä oppimistavoitteista

  • Määritä onko liuos hapan vai emäksinen.
  • Aseta hapot ja emäkset suhteelliseen järjestykseen.
  • Kuvaile molekyylitasolla, kuvien kanssa, miten vesitasapaino muuttuu pH:n myötä.
  • Määritä hydroksidi-ionien, oksoniumionien ja veden konsentraatio annetussa pH:ssa.
  • Yhdistä nesteen väri pH-arvoon.
  • Ennusta (kvalitatiivisesti ja kvantitatiivisesti) miten laimentaminen ja tilavuus vaikuttavat pH-arvoon sekä hydroksidi-ionien, oksoniumionien ja veden konsentraatioon.
