Procedure method making a soluble salt from an acid and …
6b. A 2nd Method of Making a Water Soluble Salt 6b. METHOD (b) Reacting an acid with a metal or with an insoluble base to give a soluble salt e.g. an insoluble base such as a metal oxide, metal hydroxide or a metal carbonate, often of a Group 2 metal like calcium, magnesium or a Transition Metal like nickel, copper or zinc.
Sodium (Na) and water - Water Treatment and Purifiion
Sodium metal is heated and may ignite and burn with a characteristic orange flame. Hydrogen gas released during the burning process reacts strongly with oxygen in the air. A nuer of sodium compounds do not react as strongly with water, but are strongly water soluble.
water treatment – removing hardness (calcium and …
Calcium carbonate precipitation takes place with the formation of sodium carbonate that will react with permanent hardness according to reactions (5) and (6) above. Using caustic soda will, therefore, lower water hardness to a level that is equal to twice the reduction

REACTIONS OF HEXAAQUA METAL IONS WITH …
5/10/2018· The general case Although there are only minor differences, for simplicity we will look at 2+ ions and 3+ ions separately. Adding hydroxide ions to 2+ hexaaqua ions These have the form [M(H 2 O) 6] 2+.Their acidity is shown in the reaction of the hexaaqua ions with
Forming a Precipitate | Chapter 6: Chemical Change | …
After the water evaporates, the calcium carbonate will be a white powder. Note : If you’d like to separate the sodium chloride from the water that flowed through the filter, pour the liquid into a clean empty cup and allow the water to evaporate for a few days.

gcse Reactivity series of metals, metallic activity order …
You can also determine the reactivity series of metal activity by reacting the metals with water or acids. Though the results are not always consistent with the theoretical order. For more details see section 3. Metal Reactivity Series Experiments-Observations
Summary | Reactions Of Acids With Metals | Siyavula
Siyavula''s open Natural Sciences Grade 9 textbook, chapter 13 on Reactions Of Acids With Metals covering Summary In the previous chapter we learnt about the reactions of acids with a variety of bases: metal oxides, metal hydroxides and metal carbonates.
What happens when aluminium reacts with hydrochloric …
16/6/2017· That happens because the piece of aluminium is protected by a layer of aluminium oxide, "Al"_2"O"_3, the same layer that protects aluminium from reacting with water. The hydrochloric acid will take some time to eat through this protective layer, but once that happens, the reaction will proceed quite vigorously, i.e. hydrogen gas will start to bubble out of solution.
What is the chemical equation for the reaction of calcium …
