What is meant by the term salt? And how would you confirm if the salt had chloride ions in?

Part 1: "A salt is is when the H + ion in an acid is replaced with a cation (e.g. a metal)" Part 2: You would use the silver nitrate test for halide ions. You add dilute nitric acid (which avoids g...

Explain the trend in boiling points between HF, HCl and HBr.

There are two themes in this answer. The first being the hydrogen bonding potential of HF and the second being the difference in size of the of the halide ions. Fluorine is one of three elements that can for...

A) What assumptions are made about ideal gases. B) if 14g of an ideal gas is added to a 4 dm3 container at 210Kpa pressure and a temperature of 40oc how many moles were added and suggest the identity of the gas.

The two main assumptions that are made about ideal gases are: firstly, that the volume of the gas particles themselves is negligible or zero. So, the entire volume of the container is available. Secondly tha...

In order to find the [H+] ion content of H2SO4 (Sulphuric Acid), why must you divide by two after using the formula for pH calculation?

This is because H2S04 is a diprotic acid. If we look at how the acid dissiociates, we can see that: H 2 SO 4 ----------> 2H + +SO 4 2- Since there are two H + ions dissociating, using the formula for pH w...

What are 3 characteristics of Benzene that go against the proposed Kekule model?

The Kekule model states Benzene consists of 3 pairs of alternating double C=C and single C-C bonds. A typical C=C bond would readily react with bromine to produce a dibromo-alkane and therefore would react w...
