You're trying but there's difference between gelatinous ppt and just chalky ppt and the difference is a major parameter the examiner judges. So, you must be specific. You don't just generalise the ppt. You must mention if it is ordinary or gelatinous.
Thank you so much Sir, please how do I make sodalime solution How many grams of Ca(OH)2 and NaOH in 250cm3 of water I will really appreciate a reply sir
Pls sodalime is a mixture of caustic soda(NaOH) and calcium oxide(CaO) n not calcium hydroxide pls,Ca(OH)2 which is slaked lime
To prepare 100g of sodalime, you will need to mix sodium hydroxide (NaOH) and calcium oxide (CaO) in the appropriate proportions. The typical ratio for sodalime is: - 75% sodium hydroxide (NaOH) - 25% calcium oxide (CaO) Here's how to prepare 100g of sodalime: 1. Weigh out 75g of sodium hydroxide (NaOH) 2. Weigh out 25g of calcium oxide (CaO) 3. Slowly add the calcium oxide to the sodium hydroxide in a well-ventilated area, while stirring 4. Continue stirring until the mixture is uniform and free of lumps 5. Store the sodalime in an airtight container, protected from moisture and air Note: Wear appropriate protective gear, including gloves, goggles, and a lab coat, when handling sodium hydroxide and calcium oxide, as they can cause skin and eye irritation. Remember to follow proper safety protocols and handling procedures when preparing and using sodalime.
30g of NaoH 18.5g of Ca(OH)2 Can't I do this in 250cm of water
Please what about alternative A
Please how can i prepare methyl orange indicator please i need reply sir
Kindly delete this table. It is a mess. Your final is 21.00 and your initial 0.00... How did you arrive at 24?
I'm very sorry for the error. I was working with a template from a previous work, then I hurriedly forgot to edit it properly. Do bear with me.
Thanks for the teaching sir❤
Man u just save a soul

Thank you
You're welcome
Love from india sir respect clear my concept subscribed❤

From the mixture 2ci can you said white gelatanous ppt
No, it's not gelatinous. Pb2+ and Ca2+ are chalky while Al3+ and Zn2+ are gelatinous. Thank you, and please do subscribe.
Please fix the final values, it's 0.0149 × 0.025 = 0.0003725 Approximately = 0.000373
Thank you very much for your observation. I sincerely appreciate that.
