Acids and Bases Question

Question on acids:


Hydrogen chloride has a boiling point of –85oC.

(a) Explain, in terms of structure and bonding, why hydrogen chloride 
has low boiling point.

(b) Hydrogen chloride dissolves in water to form and acidic solution.

Write the formula of the ion responsible for the acidity.

(c) Is this solution a strong or weak acid?

(d) Does this solution conduct electricity? Briefly explain why.

(e) Calculate the mass of hydrogen chloride which should be dissolved in 
100 cm3 of water to give 1.00 mol/dm3 of HCl(aq).

(f) When 100 cm3 of 1.0 mol/dm3 of HCl(aq) is added from a burette to 
50 cm3 of 1.0 mol/dm3 of NaOH(aq), which is in the conical flask, 
state the chemical formula of the compounds present in the final mixture. 
Sketch the pH titration curve with pH on the y-axis and volume of HCl added 
on the x-axis.

(g) Write the ionic equation of the reaction happening in (f).

(h) Which of these will turn a strip of moist universal indicator paper red, 
HCl(g) or HCl(aq)?

* Tips for 2024 O Level Chemistry Students

[Updated in 2023] Hi all,   Welcome to my international Chemistry blog. .  :)   You are free to look around and find information that you may use in your course of study. My O and A levels Chemistry blogs have hit more than 1 million pageviews as on November 2023. Thank you readers for your support!! I am so happy and humbled by this experience. I am honored to serve you as we continue on life's journey..   For 2023 Secondary 3 students under the new Chemistry syllabus, students may wish to get a hold of the older Chemistry Matters 2nd edition written by Tan Yin Toon, because the latest 3rd edition textbook by Marc Chang and other authors, is not written as rigorously as the 2nd edition. Students may like to refer to the 2nd edition Chemistry Matters textbook if the explanations in the 3rd edition are not lucid. Students who read the latest Chemistry textbook may like to read it when they are on a full stomach, because this textbook has many references to food.   For
