The metal that cannot displace hydrogen from dilute hydrochloric acid. Answer: (1) Iodine crystals (2) CO 2 (3) Metals like Cu, Ag and Au are less reactive than hydrogen; hence these metals cannot displace hydrogen from dilute hydrochloric …

A colourless, acidic gas turns lime water milky is: - Vedantu

WitrynaWhen dil. Sulphuric acid is added to sodium carbonate and heated, a colourless, odourless gas is evolved. This gas is C O 2 . When C O 2 is passed through lime water, it turns like water milky due to the formation of calcium carbonate. Also this gas doesn't show any effect when passed through K 2 C r 2 O 7 solution. Limewater is the common name for a saturated aqueous solution of calcium hydroxide. Calcium hydroxide, Ca(OH)2, is sparsely soluble at room temperature in water (1.5 g/L at 25 °C ). "Pure" (i.e. less than or fully saturated) limewater is clear and colorless, with a slight earthy smell and an astringent/bitter … Zobacz więcej An experiment commonly used to demonstrate the interaction of CO2 and Ca(OH)2 is as follows.
