Type of Oxide Version en ligne pH can be measured using Universal indicator solution which produces a rainbow of colors and classifies solutions as acidic, basic or neutral. Soluble oxides can dissolve in water to form acidic, basic or amphoteric solutions. These solutions can then become involved in neutralization reactions, which involve moving the pH of a solution towards 7 par Vikas Magare 1 Which of the following oxides exist in a different physical state at room temperature to the others? a CO2 b K2O c NO2 d SO2 2 Which of the following is not the result of acid rain? a Damage the limestone buildings. b Damage to the ozon layer. c Death of fish in lakes. d Death of forests. 3 Which of the following are not classified as fossil fuels? a OIL b Coal c Natural Gas d Wood 4 Complete the product side of the following equation: a CO2(g) + H2O(aq) + 2 NaCl(s) b CO2(g) + NaCl(s) c CO2(g) + NaCl(aq) d CO2(g) + H2O(l) + 2NaCl(aq) 5 In the experiment video, 30cm3 of hydrochloric acid is measured out carefully using a measuring cylinder. Which of the following instruments would be even more accurate for measuring the volume of the acid? I a beaker II a burette III a glass pipette a II and III b II only c I and II d I, II and III. Check 6 What is the correct chemical equation for when lithium oxide is added to water? a Li2O + H2O → 2LiOH b Li2O + H2O → LiOH + O2 c LiO + H2O → 2LiOH + H2 d Li2O + H2O → LiOH 7 Which oxide is responsibel for acid rain? a SO2 b Na2O c CO2 d P2O5
