Volume of sodium hydroxide solution = 25.0 ÷ 1000 = 0.025 dm 3 Number of moles of sodium hydroxide = concentration × volume Number of moles of sodium hydroxide = 0.3 mol/dm 3 × 0.025 dm 3 ...

{volume~in~dm^3}\) The units for concentration can also be shown as g dm-3, but this means the same as g/dm 3. 8 g of sodium hydroxide is dissolved in 2 dm 3 of water. Calculate the concentration ...

Also, the calcium hydroxide produced forms a white solid ... producing a flame and smoke. The sodium also reacts pretty strongly with the weaker concentration of hydrochloric acid. The demonstration ...
