Q1. Salts of which of the following elements provide colours to fireworks?
Explanation
Option (c) is correct: Strontium salts (e.g., strontium carbonate or strontium nitrate) are used to produce red color in fireworks. Barium salts (e.g., barium nitrate or barium chloride) are used to produce green color in fireworks. Options (a), (b) and (d) incorrect:
Zinc and Sulphur are not typically used for color in fireworks. Zinc can be used in fireworks for producing white sparks, but not for color. Potassium and Mercury are used for purple or lilac colors, but mercury is generally not used due to its toxicity and environmental concerns. Chromium and Nickel are not commonly used for coloring in fireworks. Chromium compounds can be used for green, but they are less common compared to barium and strontium.
