Question

Is lime water an acidic or basic solution?

Answer 1

Hint: To solve this question, first we need to know or understand the chemical formula or nature and its properties in the water. Also, traditionally the ‘Lime water’ is also known as the ‘Milk of lime’ due to its off-white milky colour.

Complete Step By Step Answer:
So, now let’s have a look at the chemical formula of the ‘lime water’
So basically, lime water is nothing but a common name for the dilute aqueous solution of calcium hydroxide i.e. the chemical formula is $ CaOH $ .
Lime water is partially soluble in water at room temperature. It has a bitter taste and also has a characteristic earthy smell.
However, the lime water is clear and colourless.
MPs important point to note here is that it has a ph. of $ 12.4 $ , since we know that ph. $ 12.4 $ indicates basicity. So we can say that the lime water is highly basic in nature, it shows the property as any base would do, it neutralises the civic solution quite well.
So, the correct answer to our question is that lime water is a basic solution.

Note:
It is important to note that lime water is of significant use in laboratories. Basically in the laboratories, the lame water is used to detect the presence of carbon dioxide i.e. $ C{O_2} $ . When the carbon dioxide passes through the lime water, the colourless lime water quickly changes into the milky colour and the production of this milky colour is the signal for the presence of Carbon-dioxide.
