good job

[@guccifaith5304]

Thank you so much for once I finally understood the topic😌

[@Mr.Kunguchemistry]

Most welcome 😊

[@AJANG-MAYEN]

I found your lesson on organic chemistry n that is when I began downloading almost all the videos in your channel..thanks in advance

[@Mr.Kunguchemistry]

Welcome!

[@najmudhinabdi4635]

May God bless the work of your hands I have actually understood the topic

[@Mr.Kunguchemistry]

Amen

Clear

[@buron4charlesug]

Also if i have a powder and crystals, how do i write my observation basing on texture

[@bisongben5988]

Thanks alot

[@Mr.Kunguchemistry]

Welcome

[@ismailabdi6288]

Please project the voice

[@alitwalib19]

Good job sir.....in the 6th portion, can u say effervescence occurs too?

[@margaretmidika1554]

Yes

[@gemmablac7290]

Pls do more

[@Mr.Kunguchemistry]

Noted Gemma

[@imranmohammed5535]

Sir in the fourth portion you added ammonia solution it didn't form a white precipitate it was colourless??

[@Mr.Kunguchemistry]

May be the camera didn't capture well however the ppt formed from ammonia and aluminium ions is faint.

[@mildredawuor3824]

I'm also getting confused on that🤔..... I never saw the white ppt it was just colorless

[@chileshekangwaluo1960]

Hello sir very nice explanation, do you teach extra lessons in person I would really love u to start toTuitor me in science both physics and chemistry

[@mahathussein1436]

How is it observed ; I mean wetha soluble or insoluble in excess

[@Mr.Kunguchemistry]

The suspended particles(precipitate) dissolves and a clear solution is formed

[@nicholasandera3092]

Help me with chem test paper 3plz

[@buron4charlesug]

Thank you for this platform but i a question.
How do i write my observation if am given a mixture of substances basing on colour eg (green and white, brown and blue)

[@buron4charlesug]

Also if i have a powder and crystals, how do i write my observation basing on texture

[@Mr.Kunguchemistry]

Green; Cu2+/Fe2+ Brown; Fe3+ ;Blue Cu2+

[@Mr.Kunguchemistry]

Further tests can be used to identify specific ions.

[@buron4charlesug]

What i meant is that in the observation should i write that its a "white green substance" if am given a misture of white and green substance
Also if its a mixture of powder and crystals do i say "a powdery crystalline substance" or i choose one of the textures.
Thank you

[@Mr.Kunguchemistry]

@@buron4charlesug a rare scenario though write a green- white mixture. Or a mixture of crystalline and non crystalline substances

[@hxn863]

Mwalimu what happens when you add dilute nitric(v) acid followed by lead(ii)nitrate?

[@Mr.Kunguchemistry]

Nitric acid eliminates carbonate ions (CO32-) and sulphite ions (SO3 2-).If a precipitate is formed on addition of lead ii nitrate with no fizzing on addition on nitric V acid the inference will be SO4 2-,Cl- ,Br- present . Can also add (CO32-,SO3 2- absent)

[@hxn863]

@@Mr.Kunguchemistry thank you sir

[@chimoneychimoney1061]

Sir pls wat is the name of the salt K

[@Mr.Kunguchemistry]

aluminium sulphate

[@Juniorblackmamba]

Mwalimu why have excluded lead ion from white ppt soluble in excess of NAOH

[@Mr.Kunguchemistry]

Initially we confirmed Sulphate present and asoluble salt present. Simply a soluble Sulphate. Lead Sulphate being insoluble is excluded

[@simplyMr1]

@@Mr.Kunguchemistry thanks sir

[@kikiwanjiru7928]

What salt was used in the process

[@Mr.Kunguchemistry]

aluminium sulphate was analysed

[@joo5273]

Sir is it distilled water or normal water

[@Mr.Kunguchemistry]

Strictly distilled water. Tap water may contain other ions

[@mohamedissack5974]

Teacher izt form 3 or form 4

[@Mr.Kunguchemistry]

Concepts in form 2,3 and 4

[@belaachie1244]

Sir here u added pd2nitrate so which one now is been precipitation?

[@belaachie1244]

A cation or anion because we have Pb2+ and NO3- what is now forming a white ppt in solution?
