Please could someone give me a link to a site that explains waht an alkali is? thanks

I don't know of a site BUT I probably can find one if you really want it. However, an alkali is simply a base such as NaOH or KOH, or lye. If you still want me to look for a site I shall be happy to do so.

What you told me is ok. Thank you!

You're welcome! I'm glad I could help. If you'd like to learn more about alkalis and their properties, I can explain it further.

An alkali is a type of chemical compound that is a base and can dissolve in water. It is characterized by having a pH value greater than 7, which makes it basic, as opposed to acidic substances that have a pH value lower than 7. Alkalis are often used in various industries and applications, such as in cleaning products, agriculture, and manufacturing.

If you want to explore this topic in more detail, you can search for websites or online resources that provide information about alkalis. You could use search engines like Google and enter keywords such as "what is an alkali" or "alkali definition" to find relevant sites. It's always a good practice to visit reputable sources like educational institutions, scientific organizations, or reputable chemistry websites for reliable and accurate information.

Remember, it's important to critically evaluate information from different sources and verify facts to ensure you're getting accurate and reliable information.
