Thank you

[@AbehCyndye]

I want the other video

[@user-zr6mm4gh2e]

Thanks but we want more tips for the exam

[@mamaSolange-bg3vq]

Please for thé video

Will the GCE board provide us with litmus papaer?

[@HumbleMak]

Yes

[@user-uh4uv6fv2g]

Please help with the video on how to use the inference booklet

[@HumbleMak]

I'll make it shortly

@@HumbleMak Please if there is also some important things we need to take note for BIOLOGY and PHYSICS PRACTICALS , 🙏🙏 please Make video also on it

Please for the video for the use of inference book

[@HumbleMak]

Ok just keep an eye on the channel, I'll post it there shortly

Please do we use litmus paper only in the case of heating?

[@HumbleMak]

No; sometimes the question will tell you to dip the litmus in a dissolved solution of the salt

[@user-uh4uv6fv2g]

@@HumbleMak Okay, thank you But if I can remember, it's like you said before heating we need to dissolve the litmus paper in water? It's any clean water right 🙏🙏

[@user-uh4uv6fv2g]

Please there is no effect on heating or Solubility in excess reagent with the halide ions

[@HumbleMak]

If you add in excess all the precipitates will not dissolve

[@user-zr6mm4gh2e]

Please show how find the slope of curves on energetics

[@HumbleMak]

Ok

Ok

Do we eliminate some ions as we proceed? Please explain

[@HumbleMak]

Ok I will

@@HumbleMak - Magnesium sulphate - Barium chloride followed by Dil HCl - Silver Nitrate followed by Dil HNO3 Please are there other reagents apart from this other reagents to test for the presence of Anions

[@user-uh4uv6fv2g]

Please what is the answer to the question Do we eliminate some ions as we proceed?

[@HumbleMak]

Initially you might ba asked to add NaOH or NH3 . Their reason for doing so is to test for cations. Many cations might have the same expectations meaning more than one cation might give an insoluble white precipitate etc. And you'll need to write all of such cations now the next step might want you to do more tests and the main aim is for you to eliminate the others and have just one as your resultant cation. So the elimination starts from top till butom
