Igcse Model Questions Vol1 2020 Chemistry Question 3
Practice practical question 3 from the 2020 Igcse Model Questions Vol1 Chemistry examination. This question covers Chemical Bonding, Ionic Compounds, Conductivity, Solubility .
A white crystalline solid labelled “A” is provided for investigation. The following observations are recorded during the practical investigation: • Appearance: white crystalline solid, colourless. • Melting point: 801 °C (high). • Solubility: soluble in water, forming a colourless solution. • Conductivity of the aqueous solution (0.10 mol L⁻¹): 15 mS cm⁻¹ (moderate). • Conductivity of the molten solid (measured with a high‑temperature conductivity probe): high. • When a few drops of dilute HCl are added to the solid, no visible reaction occurs. • When a few drops of the aqueous solution are added to silver nitrate solution, a white precipitate forms. Using the data above, answer the following questions:
