This is supportive of my conclusion. Many can cause combustion if mixed with an oxidisable combustible material. Limescale is the build—up of a limestone like deposit in areas of hard water.

The alkali sodium carbonate is used in making glass. There are 2 outliers Improvements and further investigations: It can also be found in the stomach.

Limescale is the build—up of a limestone like deposit in areas of hard water. Citric acid is found in citrus fruits and is used as a food and drink flavouring, as is tartaric acid. See hazard warning signs further down the page and also " Investigation of Indigestion Tablets ".

I have used reliable resources to research this information and it all confirms my conclusion. The strong alkali sodium hydroxide NaOH is used bleaches and other cleaning products.

As you say, there are many possible ways that the understanding of practical science could be tested and added to or integrated into the current exams.

The timer was stopped when in see the black cross through the cloudy solution could no longer. An acid solution is defined as one with a pH of less than 7, neutral solutions have a pH of 7 or as near as make no difference if the solutions has acidic or alkaline properties and alkaline solutions have a pH of over 7.

For every one M increase, the rate for reaction increases by 2. However, what is known is that i bees and wasps have glands that can secrete either acids or alkalis with other substances and ii ants sting venom often contains methanoic acid 'formic acid' which can have a pH of 3 and is presumably 'soothed' by mild alkalis and just to confuse matters more, iii many people claim the 'folklore' remedies work.

It should be pointed out that sting venom is a complex mixture, including many protein—enzymes, which, with other 'foreign' substances, might well trigger a response from the bodies immune system, so, in all honesty, I'm not quite sure what the truth is.

Also includes substances like bromine. However, as mentioned above, if you produce too much acid you get indigestion and need to take an antacid indigestion tablet to neutralise the excess. For example, rusting is a slow reaction; it has a low rate of reaction.

Eventually harmless calcium sulfate solution is formed. An input of heat energy is required to start some reactions.
