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!).

What makes different types of water different?
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.
What color will the water go if you add litmus?
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.
How is H2O different from the elements that make up water?
Water is different from hydrogen and oxygen in the same way that wood ash is different from wood and oxygen. Both water and wood ash are the products of combustion.
Do detegeant and soap has the same effect on different types of water?
no. soap cannot be used in hard water
Which has greater density 3 kg of water or 7 kg of water?
They will both have the same density, but have different volumes.
Study the acidity of different samples of tea?
i 2 want d same answer
How is conventional sources of energy different from conventional sources?
Conventional sources are the same as conventional sources.
Why might different secondary sources make sources contradictory claims about the same event?
people have different interpretations of primary sources
Does water from different sources have same acidity?
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!).

Do all chemicals have the same effect on red cabbage?
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.
Are there different water masses?
pure water has the same density, and the same mass
Why might different secondary source make contradictory claims about same event?
people have different interpretations of primary sources
How do you cite a source in your essay when two different sources have the same title?
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.
Will the density or water be the same if different groups start with different amounts of water?
yes, density stays the same regardless of amount
Why is it harder for a historian to use sources than for a detective?
Historians often deal with incomplete, biased, or conflicting sources, making it challenging to piece together an accurate narrative. Unlike detectives who may have access to physical evidence, historians must interpret and analyze historical documents to construct their understanding of the past. Additionally, historical sources may be limited by the perspectives or agendas of their creators, requiring historians to critically evaluate their reliability.
Why is it harder for a historian to use sources than for a detectives?
Many sources that historians use are not as reliable as those used by a detective. They have to compile different sources from the same era to determine their accuracy.
