Potassium, sodium, lithium and calcium all react violently with dilute sulfuric acid and dilute hydrochloric acid. It is dangerous to put these metals into an acid. The reaction is similar to the reaction with water, forming the metal salt (either sulfate or chloride) plus H
A solution of a metal hydroxide of formula MOH was prepared by dissolving 5.0g of MOH in 1 dm 3 of water (M is an unknown metal). 25 cm 3 of the MOH solution required 22.3 cm 3 of the HCl acid solution to neutralise it in a titration procedure using a pipette (MOH) and burette (HCl).
is calcium alkaline ??? | Yahoo Answers
9/8/2019· Calcium is a metal. It is neither acidic nor alkaline. But - if the Ca metal is reacted with water , the following occurs Ca+ 2H2O → Ca(OH)2 + H2 The Ca(OH)2 produced is sparingly soluble in water . But being a Gr11 metal hydroxide , it produces a basic or
Strontium (Sr) and water - Lenntech
Seawater contains 8 ppm strontium on average. River water generally contains about 50 ppb of strontium and in oyster tissue 10 ppm of strontium (dry mass) was found. When dissolved in water strontium mainly occurs as Sr 2+ (aq). One other possible form is SrOH + (aq).

Sodium in Water Chemistry Demonstration - ThoughtCo
28/10/2019· The sodium in water chemistry demonstration is a spectacular demonstration that illustrates the reactivity of an alkali metal with water. What to Expect A small piece of sodium metal will be placed in a bowl of water. If a phenolphthalein indior has been added to the water, the sodium will leave a pink trail behind it as the metal sputters and reacts.
