Abridgements it was noticed when opening the water faucet from the pot of water heater in the house change the color of water, questions were asked about why the color of the water and whether this variable water color suitable for human! . Therefore, research was conducted to determine the validity of the use of water affected by rust rust-colored Water is a natural resource that exists in nature in limited quantities. Its distribution is linked to various factors such as climate, the extent of the earth's storage capacity, the natural resource availability availability and its irregular distribution in space and time makes it a natural natural heritage The importance of water is due to its association with human civilizations throughout history; Most of the Kingdom's cities rely on renewable surface, deep groundwater and seawater desalination plants. Compare (for pure water, rust - colored water, for water that has been nominated) in terms of several faces when proven temperature and volume The tests have shown that rust has changed the color of the water Rust will not harm our health if it is in small quantities If it is in large quantities and at intervals of time spaced, it may lead to kidney problems may reach kidney failure, stomach problems, colic Severe pain, facial pallor, circulatory problems which is one of the leading causes of cancer, may become part of the water coming to our homes, and can enter iron into drinking water by eating iron or pipe wells Rust-stained water is often contaminated because water pollution is any change of natural qualities in the water by adding any strange substances that cause it to be disturbed or to gain color, smell or taste . Therefore, it is recommended to do periodic maintenance of the heater to remove the sediment and put the filter device and adjust the heat of the heater Keywords: water, rust, heater. Table of contents Effect of rust in water Research questions 1 Introduction and Hypothesis 2 Materials and Methods of Notes 3,4,5 Analysis, conclusion and discussion 6 Thanks and appreciation 7 References 8 Research questions ؟Is water contaminated when there is rust What is the normal amount of rust in our water ? ؟What is the difference between rust-colored water before and after filtration? Experiment Method Tools 1- Cup - Spherical flask - Suppression - Filter paper 2-Devices: Electrical conductivity measuring device - pH measurement device and temperature - Oxygen and nitrate concentration tubes 3-3 - Steps of the experiment ) Sample (1 Place the pure water in the cup Taking measurements: pH (temperature) - temperature - electrical conductivity concentration of nitrates - concentration of oxygen Sample (2) The colored water is rusted in the cup Taking measurements: pH (temperature) - temperature - electrical conductivity - concentration of nitrates - concentration of oxygen Sample(3) Fold the filter paper properly and place it in the funnel- Place the funnel inside the ball beake- Stained water is rusted by 600 ml- Wait 30 minutes for filter paper to be filtered - -Taking filter water measurements (PH - temperature electrical conductivity - concentration of nitrates concentration of oxygen Materials and Methods of Notes The comparison between pure water, water stained with rust, water that was nominated in terms of several faces when proven temperature and size and the results were as follows: Comparisons Pure water Stained Water is nominated transparency transparent Non transparent transparent Commission degree 8.9 8.9 8.9 Electrical conductivity 155 184 188 Concentration of oxygen 6 6 4 Concentration of nitrates 0 0 0 Comparison of rust water and water without rust Analysis and discussion It was found that the rust is a heterogeneous solution and that when the temperature and volume were confirmed, the effect of rust on the water in a number of changes, including color change, oxygen ratio and electrical conductivity. When filtering the rusted water, we found that the rust ratio was 77% through equation (2.88-2.11 = 0.77, 0.77 × 100 = 77%} This ratio is large Conclusion After testing and research we found that the rust caused the water color change, rust will not harm our health if in small quantities either in large quantities and at intervals of time spaced, may lead to kidney problems may reach kidney failure, stomach problems, colic Severe pain, facial pallor, circulatory problems which is one of the leading causes of cancer, may become part of the water coming to our homes, and can enter iron into drinking water by eating iron or pipe wells . Rust-stained water is often contaminated because water pollution is any change of natural qualities in the water by adding any strange substances that cause it to be disturbed or to gain color, smell or taste. Therefore, it is necessary to maintain periodic circulation of the heater to remove the sediment and put the filter device and adjust the heater temperature. Discussion Therefore, it is necessary to maintain periodic circulation of the heater to remove the sediment and put the filter device and adjust the heater temperature Thanks and appreciation Finally, we would like to thank everyone who helped us to reach this successful stage of our lives.
