1.
Which ion do all acids release in water?
H+
OH−
Cl−
O2−
2.
A solution of pH 13 is:
strongly acidic
neutral
weakly acidic
strongly alkaline
3.
Which statement best describes Alkali?
Titres that agree closely, usually within 0.10 cm3 of each other.
A base that is soluble in water and releases hydroxide ions, OH−, in solution.
A scale from 0 to 14 measuring acidity or alkalinity; 7 is neutral.
The reaction of an acid with a base to form a salt and water: H+ + OH− → H2O.
4.
Which statement best describes Neutralisation?
A method to find the exact volume of one solution that reacts completely with a known volume of another.
The reaction of an acid with a base to form a salt and water: H+ + OH− → H2O.
Titres that agree closely, usually within 0.10 cm3 of each other.
A scale from 0 to 14 measuring acidity or alkalinity; 7 is neutral.
5.
Which statement best describes Universal indicator?
The point in a titration when the indicator changes colour, showing neutralisation is complete.
The reaction of an acid with a base to form a salt and water: H+ + OH− → H2O.
A substance that releases hydrogen ions, H+, in aqueous solution; a proton donor.
A mixture of indicators that shows a range of colours, giving an approximate pH value.
