hello again i can not get my starch transparent maybe bc i am using cornflower ? should i use different starch? thx

I guess yes. I use "soluble starch" most probably prepared from potato

hello my friend because you're in chemistry I would like to know is there any way to make transparent starch solution? because I tried to filter it and it doesn't work .thx
@chatzida 2 ай бұрын
I prepare my 2% starch solution in a way that it is transparent. I boil 100 mL of water in a beaker (beaker A), and in a separate beaker (B) I weigh 2 g of starch. Then I add a very small amount of room temperature water on the starch and I mix with a glass rod to make a slurry (not a solution). It is important to add the proper amount of water; we do not want starch powder nor solution but a slurry. Then I pour the hot water of beaker A to beaker B and stir thoroughly with a rod or magnetic stirrer. The resulting starch solution is transparent! But keep in mind that starch solutions are not preserved too long because bacteria and fungi love them!

Αρχικά θα ήθελα να σας πω ένα μεγάλο ευχαριστώ!! Θα ήθελα όμως να μου λύσετε μία απορία για την ασκηση 3... Μπορώ να βρώ την μάζα μόνο απο τον τύπο mol = m/ ΜΒ; Δηλαδή να γίνει: m=mol x MB=3 X 40= 120gr. Μετα όμως πως βρισκουμε το 60gr;
@chatzida 5 ай бұрын
Τα mol του NaOH δεν είναι 3. Η συγκέντωση, c, είναι 3 Μ. Μπορείς να βρεί τα mol με τη σχεση n=c*V που εδώ είναι n=3*0,5=1,5 mol. Μετά εφαρμόζεις την n=m/Mr => m= n*Mr=1,5*40 = 60 g

Τι κριμα να διδασκομαστε φυσικη και χημεια στο λυκειο χωρις πειράματα. Πραγματικά κριμα. Το εκπαιδευτικό σύστημα ειναι σκατα και οι υποδομες επισης. Εμεις ειμασταν τυχεροί διοτι τοσο στο γυμνάσιο οσο και στο λυκειο ειχαμε εργαστηριο πληρως εξοπλισμενο, πραγμα οχι τοσο συνήθες για ελληνικα δεδομένα. Ωστόσο,.λογω έλλειψης χρόνου (ισως και διαθεσης?) οι καθηγητές μας δε μας έκαναν πειράματα σχεδον καθόλου. Τρεχαν να βγαλουν την υλη...

Εξοπλισμένο εργαστήριο έχει η μεγάλη πλειοψηφία των Γενικών Λυκείων. Βέβαια σε κάποια σχολεία έχει μετατραπεί σε αίθουσα μαθημάτων και σε κάποια έχει απλώς μείνει αναξιοποίητο. Αρκετοί όμως εκπαιδευτικοί βλέπουμε το πείραμα όχι απλά σαν απαραίτητο εργαλείο στην κατανόηση της θεωρίας αλλά και σαν μια δραστηριότητα που ξυπνά το ενδιαφέρον των μαθητών για να ασχοληθούν με τις θετικές επιστήμες. Και νομίζω το τελευταίο είναι το μεγαλύτερο κέρδος...
