In yesterday (Day 2) post of? “O Levels Chemistry Tips Blog Marathon” series, we have discussed on the important concepts that GCE O Levels Chemistry students need to know for Acids, Bases & Salts. There are also 2 basic multiple choice questions for you to attempt to see how much you understand about this chapters.
Today, we are going to?look into 2 more questions on Acids, Bases & Salts, which potentially can be tricky questions for your school’s chemistry mid-year examinations.
Question 1: Based on the topic “Acids, Bases & Salts”
Which salt can be prepared by an acid-alkali titration method?
A. Ammonium sulfate
B. Copper (II) sulfate
C. Iron (II) sulfate
D. Zinc sulfateClue: 1st step is to determine the solubility of the salt.
and
Question 2: Based on the topic “Acids, Bases & Salts”
Which of the following particles are NOT present in a carbonic acid solution?
A. CO32-(aq)
B. H+(aq)
C. CO2(aq)
D. H2CO3(aq)Clue: You need to understand on the Dissociation of Acids
As mentioned in many of my posts, “Once the student is ready, the teacher will appear” – this means that i will give my suggested answers and reasonings once i see chemistry students / readers participating in the discussion.
PS: Attempt the 2 questions above and leave down your answers & reasonings in the “Leave A Reply” below.
