What is a net ionic equation?

Back

A net ionic equation shows only the species that participate in a chemical reaction, omitting spectator ions.

Front

What is the net ionic equation for the reaction of AgNO3 and CaCl2?

Back

Ag+(aq) + Cl-(aq) → AgCl(s)

Front

Define non-electrolytes.

Back

Non-electrolytes are substances that dissolve in water but do not ionize.

Front

What are spectator ions?

Back

Spectator ions are ions that do not participate in the actual chemical reaction and remain unchanged.

Front

Which ions can be considered as spectator ions in a reaction?

Back

NH4+ and Cl- can be considered as spectator ions.

Front

How do you prepare a diluted solution from a concentrated solution?

Back

Use the dilution formula: C1V1 = C2V2, where C is concentration and V is volume.

Front

Calculate the volume of water needed to dilute 20.0 mL of 12.0 M HCl to 0.500 M HCl.

Back

You need to add 460 mL of water.

Front

How do you calculate the mass of solute in a solution?

Back

Use the formula: mass = molarity × volume × molar mass.

Front

How many grams of solute are in 125.0 mL of 5.00 M NaCl?

Back

There are 36.5 g of NaCl.

Front

What is molarity?

Back

Molarity is a measure of concentration defined as moles of solute per liter of solution.
