The pH Scale
100

This is what must happen between reactant particles for a forward reaction to occur.

What is collision?

100

This is the state reached when the concentrations of both reactants and products are no longer changing.

What is equilibrium?

100

This French scientist is known for the principle that states an equilibrium will counteract any change to the system.

Who is Henry Louis Le Chatelier?

100

This type of substance is defined as a proton acceptor.

What is a base?

100

A substance with a pH greater than 7 is known as this.

What is alkaline or basic?

200

This factor, if increased, will cause particles to move faster, increasing the number of collisions and the reaction rate.

What is temperature?

200

This value, which is specific to a particular temperature, indicates the proportion of reactants to products in a given reaction.

What is the equilibrium constant, Kc?

200

This type of reaction is favored when the temperature of a system increases.

What is an endothermic reaction?

200

This describes an acid that can donate more than one proton to water molecules.


What is a polyprotic acid?

200

This scale measures how acidic or alkaline a substance is, with each whole value being 10 times more acidic or alkaline than the next.

What is the pH scale?

300

This is the minimum amount of energy required for a collision to result in a reaction.

What is activation energy?

300

This is the direction a reaction will favor if the Kc value is less than 1.

What is the reverse reaction?

300

This type of reaction is favoured when the temperature of a system decreases.

What is an exothermic reaction?

300

These acids are much better electrical conductors than weak acids because they completely dissociate in water, creating more ions.

What are strong acids?

300

The concentration of hydrogen ions will increase exponentially as the pH value does this.

What is decrease?

400

When you increase the concentration of reactants, you increase the chance of these happening between particles.

What are successful collisions?

400

When the concentration of products is higher than the concentration of reactants, the Kc value will be greater than this number.

What is 1?

400

This change to an equilibrium system will not have an effect on the position of equilibrium.

What is the addition of a catalyst?

400

The concentration of hydronium ions determines the rate of reaction between an acid and a metal to produce a metal salt and this gas.

What is hydrogen gas?

400

The pH scale is this type of scale, where each whole value is a power of ten different from the next.

What is a logarithmic scale?

500

For a reaction to happen, particles must collide with sufficient energy and in this specific way.

What is the correct orientation?

500

In a chemical equilibrium expression, these states are excluded


What are solid and liquid states?

500

When a system is at equilibrium, increasing the concentration of the reactants will cause the system to counteract the change by favouring this reaction.

What is the forward reaction?

500

An acid with this specific pH range is considered a strong acid.

What is a pH of 0-3?

500

You can calculate this value by taking the negative logarithm of the hydronium ion concentration.
