17aThe equation for the reaction of strontium hydroxide with hydrochloric acid is shown below. Sr(OH)2 + 2HCl --> SrCl2 + 2H2O 25.0 cm3 of a solution of strontium hydroxide was exactly neutralised by 15.00 cm3 of 0.100 mol dm–3 hydrochloric acid. Calculate the concentration, in mol dm...
Many chemical reactions in aqueous solution involve ionic compounds. Only some of the ions in solution take part in these reactions. The ions that play no part in the reaction are calledspectator ions. An ionic equation is simpler than a full chemical equation. It shows only the ions or othe...
ChemistryMoles of a conjugate base in a buffer solution Homework Statement You need to produce a buffer solution that has a pH of 5.70. You already have a solution that contains 0.0200 moles of acetic acid. Using the Henderson-Hasselbalch equation calculate the moles of sodium acetate needed to...

How many moles of gas are present in a 10.0 liter sample at STP? How can you determine how many moles were produced from a given equation in chemistry? How many particles are in a mole? How do you convert from amount of substance in moles to the n...
A sample of 10 cm3 of this solution required 4 x 10-4 mol of potassium manganate (VII) for complete reaction. So that means, 1 mole of Fe2+ in FeSO4 require 4 x 10-4 mol of potassium manganate to be oxidised to 1 mole of Fe3+. Since the ionic equation shows 5 moles, than we...
