pH of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

pH is virtually a measure of the relative quantity of free hydrogen and hydroxyl ions in the water. Water that has extra free hydrogen ions is acidic, whereas water that has greater free hydroxyl ions is basic.

High pH. A waterbody is considered to have a excessive pH if pH exceeds 9 for extended intervals or with excessive frequency. High pH is much less frequent than low pH as a candidate cause, due to the fact anthropogenic sources are acidic more frequently than basic.

<h3>What increases the pH of water?</h3>

Soda ash (sodium carbonate) and sodium hydroxide increase the pH of water to near neutral when injected into a water system. Unlike neutralizing filters, they do no longer motive hardness troubles in dealt with water. Injection structures are a point-of-entry system.

What occurs when water droplets in the atmosphere become heavier than the air surrounding them can hold? A. fog B. clouds C. lig

Andre45 [30]

Answer:

D. precipitation

Explanation:

When this occurs it causes precipitation, also known as rainfall. This is all part of the water cycle. Heat from the sun heats up the water on land to the point where it evaporates and accumulates and condenses in order to form clouds. Then as mentioned in this question the water droplets in the atmosphere become so heavy that the air cannot hold them and they drop in liquid form back down to the Earth until the process is repeated.

The value of the Solubility Product Constant for lead phosphate is ____________

emmasim [6.3K]

<u>Answer:</u> The reaction for the $K_{sp}$ value of lead phosphate is given below and the value of solubility product for the same is $3.0\rightarrow 10^{-44}$

<u>Explanation:</u>

Solubility product is defined as the product of concentration of ions present in a solution each raised to the power its stoichiometric ratio. It is expressed as $K_{sp}$

The chemical formula of lead phosphate is $Pb_3(PO_4)_2$

The equation for the hydration of the lead phosphate is given as:

$Pb_3(PO_4)_2(s)+H_2O(l)\rightarrow 3Pb^{2+}(aq.)+2PO_4^{3-}(aq.)$

The solubility product of lead phosphate is $3.0\rightarrow 10^{-44}$ . This means that it is highly insoluble in water as the solubility product is very very low.

Hence, the reaction for the $K_{sp}$ value of lead phosphate is given above and the value of solubility product for the same is $3.0\rightarrow 10^{-44}$
