Aurreko konparaketan ikusten den moduan, gure solido problema aztertzerakoan lortu ditugun balioak eta Azido askorbikoaren erreferentziazko balioak bat egiten dute.
Ondorio honetara iristeko, analisi lagungarriena eroankortasuna izan da, datu klabea izan baita. Izan ere, beste ezaugarri guztiekin aukera posibleak asko murriztu ditugu, baina eroankortasunak, esku artean zer substantzia genun determinatzen lagundu zigun.
Hala ere, aipatu beharra dago lortutako balio batzuk ez daudela erreferentziazko balio horien barnean. Hain zuzen, analisiak burutzerakoan zenbait errore egin direlako, sistematikoak edota giza erroreak ere. Datu horien barnean ez egon arren, asko hurbiltzen dira eta Bitamina C dela ondorioztatzeko ezinbestekoak izan dira.
The first division between continents was made by ancient Greek navigators, who named them 'landmass, terra firma'.
Generally classified by convention rather than any strict criteria, nowadays seven regions are regarded as continents from a geopolitical point of view.

Antarctica is not only the coldest place on Earth but also the highest, driest, windiest and emptiest, completely covered with ice.
75% of the world's ice and 70% of the Earth's fresh water is located here.
Summer months of December to February give 24 hours of light, while the winter months of late March to late September are pitch dark the whole day.
There are no permanent inhabitants, except for scientists maintaining research stations in Antarctica.
Helburua
Solidoa azidoa edo base den jakitea pH-metroaren bidez, haren konposizioa kimikoa nolakoa den ezagutzeko.
Oinarri Teorikoa
pH<7= Azidoa, pH=7 neutroa eta pH>7=Basea
pH=-log(H+)

North America has five time zones and it is the only continent with every type of climate.
North America was named after the explorer Amerigo Vespucci and is also known as the 'New World'.
The world's largest sugar exporter among the seven continents - Cuba - also called the 'sugar bowl of the world' is located here.
Erreferentziazko balioak vs gure balioak:
Hona hemen, Azido Askorbikoaren molekularen irudia, lortu ditugun emaitzek zentzu gehiagorekin ikusteko, molekularen konposizoa, ordena eta egitura ikusiz.
What are the major animals found in Africa?
Also, there are a few species that can be found only in Africa.
Name at least 6 of these animals.

Piknometroaren bidez gure solido ezezagunaren dentsitatea kalkulatu
Oinarri teorikoa
Dentsitatea kalkulatzeko, disolbagaitza den likido batekin nahastu da, gure kasuan etanolarekin. Dentsitatea= masa(g)/bolumena (mL)

Asia is the world's largest continent of the seven continents in size, as it covers one-third of the earth's surface.
It includes 50 countries, and it is the most populated continent, 60% of the total population of the Earth lives here.
Name as many as you can out of the 48 countries located in Asia.
Write down the capitals too.
Helburua
Gure solidoa indetifikatzeko apolarra edo polarra eta organiko edo ezorganiko den determinatzea.
Oinarri teorikoa
Solidoa+ H2O = Polarra
Solidoa + HCl = Ez organikoa
Solidoa + Hexanoa = Apolarra
Solidoa + Etanola = Disolbagaitza

Europe is separated from Asia by the Ural mountains and the Caspian Sea.
It is surrounded by water on three sides: Mediterranean Sea in the south, Atlantic Ocean in the west, and the Arctic Ocean in the north.
Three-fourth of the world's potatoes grow in Europe.
Europe has many exceptional animals, birds, and reptiles with unique methods of staying and hunting.
Name at least 4 of them.
