No. While ideally water should be pH 7 (neutral), the source may make the water acidic or alkaline. One lake in Virginia Beach Virginia has water that was prized for use aboard early sailing ships. It has high levels of tannic acid from the cypress trees in the lake- and it stayed fresh longer aboard the ships. (Looks like iced tea because of the tannin in it!).
No, lactose and nitrate are not the same. Lactose is a type of sugar found in milk and dairy products, while nitrate is a compound found in certain vegetables, water sources, and processed meats. They have different chemical compositions and functions in the body.
In principle, all water is the same. The quality that differentiates multiple forms of water, i.e. "hard water" or "soft water" is the type or volume of minerals or contaminants diffused in the solution. All water is the same on a molecular basis, but most water contains amounts of other minerals or chemicals. An example would be chlorine, which is added to many water sources to kill bacteria.
Fresh water refers to water with low levels of salinity, typically found in rivers, lakes, and groundwater sources. Clean water, on the other hand, refers to water that is free from pollutants, contaminants, and impurities. Fresh water can be clean if it is free from contaminants, but not all fresh water sources are necessarily clean.
The water should stay the same colour if you are using litmus paper, but if you are using a liquid the colour should change. The colour purely depends on the acidity/alkalinity of the water you are putting it in. Yellows are alkaline, Greens are neutral and Blues are acidic (it may be the other way around.. yellow being acid, blue being alki.) The measure of acidity is pH.
No, sweet and sour tastes are different sensations experienced on the taste buds. Sweet taste is associated with sugars, while sour taste is associated with acidity. Each taste is detected by different taste receptors on the tongue.

Yes, the water from a water fountain is typically the same as tap water, as both sources usually come from the same municipal water supply.
pure water has the same density, and the same mass
No, not all chemicals have the same effect on red cabbage. Red cabbage contains a natural pH indicator called anthocyanin, which changes color depending on the acidity or alkalinity of a solution. Different chemicals can cause different changes in color, indicating varying levels of acidity or alkalinity in the solution.
yes, density stays the same regardless of amount

How you cite a source in your essay when two different sources have the same title depends on the citation style you are using. A common way to differentiate between the two is by including the authors in the citation.
You can create four shadows with the same object by placing the object under four different light sources at the same time, each casting a separate shadow in different directions. This can be achieved by positioning the light sources in a way that they shine on the object from different angles, creating multiple shadows.
no the water levels those not stead the same
they are same because they are both part of the water cycle and different because it does different things
