AI Thread Summary
The discussion focuses on the preparation of NKBT Perovskite material with the formula (Na0.5 K0.5)0.5 (Bi)0.5 TiO3. The user seeks guidance on the correct method for calculating the required amounts of starting powders—NaNO3, KNO3, Bi(NO3)3.5H2O, and TiO2—based on stoichiometry. Key questions include whether to work in weight percent or mole percent and the validity of their calculation method for determining the grams of NaNO3 needed for a 5-gram total sample. Responses confirm that the approach of calculating molar ratios first and then converting to weight ratios using molar masses is appropriate, and the user's method for calculating the grams of NaNO3 appears correct. Overall, the emphasis is on accurate measurement and conversion for the synthesis process.

hello forum
I am working on NKBT Perovskite material.My formula is (Na0.5 K0.5)0.5 (Bi)0.5 TiO3
I am using NaNo3,KNO3,Bi(NO3)3.5H2O,TiO2 powders
my question is how much powder in grams I have to take according to stichometry.
Do I have to work in wt% or in Mole %.
is there any difference?
I am using this method
NaNO3 in Grms = molecular wt of NaNO3*no.of moles of NaNO3*5(i want to make 5 grms of total sample)/total molecular weight of compound.
Is this correct?
please reply.
actuall I am a physics major.

To prepare the mix you have to convert everything to grams, there is no other reasonable way to measure amount of the solid than to weight it.

Calculate molar ratio first, then convert it to weight ratio using molar masses of the compounds used.
 
thank you for reply
so is my method is correct? or wrong?
can I proceed in the same way?

Looks OK to me.
 

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!

Thread 'Resists for etching Aluminium with NaOH'

I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
