While the Taj Mahal does have a mosque located on its grounds, the main structure itself is a mausoleum. The mosque was built to provide a place for prayer and is located to the west of the Taj Mahal. **

The construction of the Taj Mahal is estimated to have cost around 32 million Indian rupees at the time, which is equivalent to about $1 billion in today's currency. The construction took place over a period of around 20 years, from 1632 to 1653. The cost was mainly attributed to the use of expensive materials such as white marble and precious gemstones. **

The pH value of salt solutions depends on the specific salt being dissolved. Some salts, such as sodium chloride (table salt), do not significantly affect the pH of a solution and have a neutral pH of around 7. However, other salts, such as sodium hydroxide or sodium bicarbonate, can significantly alter the pH of a solution. For example, sodium hydroxide can increase the pH, making the solution more basic, while sodium bicarbonate can act as a buffer and help maintain a relatively constant pH. **

The pH value of a solution is calculated using the formula pH = -log[H+], where [H+] represents the concentration of hydrogen ions in the solution. To calculate the pH, you first need to measure the concentration of hydrogen ions in the solution using a pH meter or indicators. Then, you take the negative logarithm of the hydrogen ion concentration to obtain the pH value. A pH value below 7 indicates acidity, while a pH value above 7 indicates alkalinity. **
